EXTREMELY FINE. THIS IS WITHOUT QUESTION THE FINEST OF THE SIX RECORDED BLOCKS OF FOUR OF THE 4-CENT PAN-AMERICAN INVERT, WHICH IS THE LARGEST SIZE MULTIPLE EXTANT.
Our records contain six blocks of four of the 4c Pan-American Invert. A seventh block that was offered in Part 17 of the Col. Edward H. R. Green auction series has since been divided into singles, two of which have been offered in our auctions. Most of the blocks have disturbed gum and minor flaws. The centering and freshness of the block offered here are unsurpassed.
Ex Wharton Sinkler, Siegel 1976 Rarities sale, 1980 Sotheby’s sale (where offered with blocks of the 1c and 2c) and 2000 Shreves sale where acquired by David Wingate. With 1980 and 2018 P.F. certificates
