"Buga" and "Franca" straight-line handstamps, cleanly handstamped on August 24, 1806 folded letter from Buga to Popayán, rated at 1½ reales for a single weight up to ½ ounce, a very fine and desirable colonial usage featuring an infrequent complete letter. (Image)

#2, #6, 1859, 5c Blue, stone A, and 20c Blue, stone B, position 40, the former slightly cut into with very good margins on other three sides, the higher denomination being well margined, on envelope endorsed “Consulate of the United States/Cartagena-New Granada" addressed to Mompós, both stamps being tied by "Cartagena/Franca" oval handstamp, "Albert Mathieu/Carthagena N.G." forwarding agent’s cachet at bottom left, being the company that usually dispatched the mail from the U.S. Consulate and consigned this cover to the Cartagena national postal administration for the journey covered by the post, the 25 c. postage being paid to cover the triple weight rate up to 20 grams of this large envelope for a distance between 150 and 450 km; small portion of paper loss in upper left corner, not affecting the appearance of this stunning item; a rarity bearing two different denominations in same color, with only six such combination frankings so far recorded, further enhanced by being one of only six postal history examples in the first issue with involvement of a forwarding agent in its carriage; 2013 Moorhouse and 2018 Martínez certificates; ex-Santa María and Hubbard.

(Image)

Est. $1,000-1,500

#C5, 1920 10c “Flier in Plane Watching Biplane”, a very fine example exhibiting large margins all around and bright color, tied by “CCNA/Agencia Barranquilla” oval handstamp, showing National Post c.d.s in blue of Cartagena dated 9 March 1920 and three-line “Visitaduría Especial de Correos/de la/Circunscripción del Noroeste” handstamp in violet from the post, the only philatelic evidence corroborating the Barranquilla to Cartagena Return-Flight of 7 March 1920, of great desirability and significance; ex-Lüning and Johnson.

Est. $1,000-1,500

#C11, 1920 10c Green, block of four featuring the basic transfers with “CCNA/Cartagena” oval handstamp; some imperfections, nevertheless a very rare block of four in used condition. (Image)

Est. $150-200

#C11, 10c Green, 6 March 1920, Third Flight, cover (upper back flap missing) to New York, flown from Cartagena to Barranquilla and then carried by maritime means to United States, franked by 1920 10c green tied by “CCNA/Cartagena” oval handstamp, with additional franking of 5 centavos to pay the national postage, tied by “Correo Aéreo./Cartagena-Colombia.” c.d.s., opened tear at base on front and couple of creases affecting the adhesive, of no importance for this unique item; this commercial cover does not only represent a very rare usage on the first day of issue, with only three covers known from this flight, but also the only cover known, bearing this issue, addressed to a destination outside Colombia, these comments clearly confirming the considerable significance and desirability of this cover; Rendon certificate; ex-Boonshaft and Johnson. (Image)

Est. $3,500-5,000

#C11, 1920 10c Green, four examples on piece, tied by “CCNA/Agencia de Barranquilla” oval handstamp, accompanied by National-Post revenue 1c and 20c; the franking would have paid a large envelope of at least 60 grams (as per 40 centavos), which was probably flown in April 1920; despite faults, a desirable item representing the third largest franking of the 10c; ex-Boonshaft. (Image)

Est. $400-500

#C11, 10c Green, 9 June 1920 Flight, tied by “CCNA/Cartagena” oval, used on piece together with National Post 3c with airmail c.d.s. on dispatch dated “Jun 9 1920”, denoting the flight to Barranquilla by Capt.

Gebauer #16, 1920 30c on 10c Green, featuring a barely visible impression of the surcharge which may have faded with time, on cover front addressed to Barranquilla, tied by “Cía de Navegación/Aérea/Agencia Barranquilla” ribbon handstamp in purple, handstamped with “22 FEB 1920” date adjacent, and bearing manuscript inscription in Spanish at left: “Souvenir of the first airmail flight. Cartagena, February 21, 1920” and signature by Mr. Soto; one of just three covers recorded exhibiting the 30 centavos surcharge on this stamp; ex-Johnson. The cover, which is not flown, was not franked with the required national postage, and the C.C.N.A. adhesive is tied by a Barranquilla handstamp which was not applied on any of the regularly flown covers. Mr. J. Soto very probably made an agreement with the C.C.N.A. and prepared a very small quantity of covers to be given to friends, although these were dated as from the First Flight of February 22. Nevertheless, one may hypothesize, and it is also believed by few collectors, that these souvenir covers were flown on the first stage (Cartagena-Barranquilla) of the flight by the “Medellín” of 30 November 1920 (the plane suffered a breakdown at El Banco), since the surcharge of 30 centavos corresponded to the C.C.N.A. Nevertheless, this hypothesis can not be demonstrated and, on the other hand, the national postage is missing. (Image)

Est. $750-1,500

1920, Third Issue 10c Green, group of six essays, featuring the characteristic dark color and thin double outer framelines, including two single examples of the two designs, and a very rare block of four in emerald-green showing the basic composite setting of the sheet and cancelled by “CCNA/Barranquilla” handstamps; wrinkles and creases, as usually encountered, are to be expected, very scarce. (Image)

Est. $300-400

Est. $300-400

#Gebauer #14-15, 1920 10c Brick-red, “Sea and Mountains” & “Cliff and Lighthouse”, the two vignettes in this color showing framed “Cía. Colombiana de Mavegación/Aérea/Agencia El Banco” cachet in violet; minor imperfections as usually encountered in these stamps in used condition; two of the three examples known bearing a usage of any C.C.N.A. handstamp of El Banco; ex-Gebauer.

Gebauer #21, “Sea and Mountains” 20c on 10c Light brown-red, typewritten surcharge, cut-to-shape example on. 1920, December 20 cover (reduced at left) from Medellin to Cartagena, tied by “Cía. Colombiana de Navegación/Aérea/Medellín” ribbon handstamp, uprated for national postage with 3c., tied by duplex datestamp of Medellin, which also ties this vignette and, at foot, part of “Agencia Postal Nacional/Cartagena Colombia” framed datestamp.A small number of vignettes were surcharged “0-20” and “0-30” with typewriter, and were to be used on the return flight of the “Medellín” from Medellín to Cartagena via Puerto Berrío. The plane, on its flight up-river, run out of fuel near San Bartolomé on the way to Puerto Berrío, after 3 hours and 30 minutes, and it was destroyed overnight by a storm. The few covers carried were consequently sent by surface mail for onward transmission.Taking into consideration the scarcity of the typewritten surcharge, and that only two covers are recorded bearing this provisional stamp, this is one of the extraordinary rarities of the early Colombian airmails; the great visual appeal of this cover is also enhanced by the only application known on cover of the embossed “Cía-Colombiana/De Navegación Aérea” publicity label illustrated with a biplane, which was also tied on dispatch; ex-Neuburger and Johnson (Image)

Est. $2,500-3,000

Illustrated on page 24 of Kessler’s “The Air Posts of Colombia”, as well as on page 48 of Eugenio Gebauer’s “The Air Post of Colombia”, where this item, together with other three covers -to the same addressee and destination city-, are illustrated, and all four are described by the famous author and editor of the book as “THE GREATEST FIND IN SCADTA STAMPS” with the following text: “A discovery in the early thirties among old office correspondence of the ‘American Woolen Products Co.’ brought to light a number of envelopes mailed by their Colombian representative in 1921. The four covers illustrated are the outstanding pieces among this correspondence showing the legitimate usage of the varieties catalogued. (...). All four covers illustrated were regularly used on business correspondence and are unique in the opinion of the Editor”. A unique trisect usage of this stamp; its desirability is further enhanced by the fact that it was used on commercial correspondence; one of the great rarities of Colombian aerophilately; Rendon certificate; exPhilip G. Cole, Gebauer and Johnson. (Image)
