12c Black (17). Positions 7-10/37-40L1, block of 16, mostly full margins to in at just a couple places, 11-bar circular grid cancels, faults including heavy partially broken crease in left column, tear in Position 17, couple rust-covered pinholes in Position 18

VERY FINE APPEARANCE. THIS IS THE SECOND LARGEST RECORDED USED MULTIPLE OF THE 12-CENT 1851 ISSUE.

This block of 16 is the second largest used multiple of the 12c 1851 Issue. The Mortimer Neinken collection contained a 9-by-2 block of 18 (Sale 384, lot 200), which was removed from a large cover before 1951 and is ex Col. Tracy and Jessup. We presume this is the item that is listed in U.S. Stamp Facts as a block of 18 on cover. The largest surviving on-cover block is a block of six in the Charles A. Hirzel collection at the Swiss Museum of Communications in Berne, Switzerland. There is also a strip of six on cover in the James A. Allen collection.

Ex Leon Adutt (Morgenthau sale, June 26-27, 1923--it realized $1,025 in this sale nearly 100 years ago) and Ishikawa. Scott value as four used blocks is $22,000.00
