1858, Medio Peso Rose Red instead of yellow COLOUR ERROR. Type C, huge margins, beautiful bright color, tied by perfect strike of "CALLAO 1-2" dotted oval on 1858 cover to Mariano Alejo Portugal, Arequipa.EXTREMELY FINE STAMP AND COVER. A SUPERB EXAMPLE OF THE MEDIO PESO ERROR AND ONE OF ONLY A DOZEN SINGLES ON COVER RECORDED BY BARGHOLTZ, of which we believe that even less than eight are without a doubt genuine. This famous ex Caspary and ex Bustamante cover is considered to be the FINEST OF ALL SINGLE FRANKINGS KNOWN (it is tied, it has the widest margins and it has never been lifted of the cover). A GREAT RARITY OF THE FIRST OFFICIAL ISSUE OF PERU. The Piura cover of the Islander collection (lot 269, untied and with smaller margins) sold in 2008 for 25.000 USD.

Certificate Brian Moorhouse: "The left hand bisect was probably applied as the original postage in Callao but the letter was deemed to be underpaid with a manuscript "5 Centavos" endorsement whereupon the right hand bisect was then added to collect the additional postage" A VERY SPECTACULAR AND UNIQUE DOUBLE BISECT COVER.
