This mint plate block of six from Scott C7, the 1926 10¢ U.S. Airmail issue, offers the classic engraved "Map of the United States with Mail Plane” design that marked the early rise of transcontinental flight. As the first stamp in the redesigned airmail series, C7 remains essential to collectors who appreciate early aviation history, engraved BEP production, and plate-number multiples from the 1920s.

The selvage is fully intact and displays Plate No. 18247 with strong clarity. The block retains rich color, precise impressions, and original gum. Mint multiples of C7 in this format continue to attract collectors who favor visually balanced plate blocks and historically significant airmail material.
