EXTREMELY FINE CENTERING. AN EXTREMELY RARE BLOCK OF FOUR OF THE 4-CENT PAN-AMERICAN INVERT. ONLY SIX BLOCKS ARE RECORDED, AND THIS IS ONE OF THE BEST CENTERED.
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 Col. Edward H. R. Green, Amos Eno and Stephen Bechtel. With 2015 P.F. certificate
