1840, 1 d. black, plate 1b, CK, large margins to just in at upper right, bright shade, tied by red Maltese Cross, matching "H 7 AU 7 1840“ backstamp on Post Magazine folded publication to Tokenhouse Yard in London, also with "Gravesend AU 7, 1840“ and receiving backstamp. Very fine, a beautiful and rare example of the Penny Black used on early edition of the Post Magazine in August 1840. A phenomenal cover, highly desirable.According to British Pictorial Envelopes of the 19th Century, in August 1840 the Post Magazine appeared. It had originally been published in 1837 as propaganda for Uniform Postage. One flap states "Remarkable application of the reduced postage, Combining 1st. A magazine of useful information, 2nd. A Post Label, 3rd. A sheet of letter paper“. This weekly news sheet was sold ready stamped with the Penny Black and charged 1 ½ d. to the public and 1 d. to advertisers. Publication appears to have ceased in early 1841 but (Image)

1840, MAGENTA MALTESE CROSS CANCELLATION, 2d. blue, plate 2, vertical pair lettered DI-EI, fresh colour and full margins all around, clearly oblit. by two strikes of MAGENTA MC (most probably from Preston but of course not verifiable). Plate 2 was brought into use towards the end of 1840, and the overlap between the use of this plate and the use of red cancellation ink was therefore small. Magenta has been recorded from several post offices, although was never an officially adopted colour. It appears to have arisen as a result of "local iniative" as red ink ran out, and replacement pigment was ordered from local suppliers. This is the ONLY KNOWN MULTIPLE of 2d. blue from plate 2. SG lists 2 single stamps of the more common plate 1 with £24000 (nota bene for plate 1!). Certificate BPA (SG spec. D1ue). A MARVELLOUS PAIR - UNIQUE AND UTMOST DESIRABLE! (Image)
