Scott C7 – 1926 10¢ Airmail Plate Block of 6 – Mint Plate No. 18248

This mint plate block of six from Scott C7, the 1926 10-cent U.S. Airmail issue, features the engraved “Map of the United States with Mail Plane” design that helped define early transcontinental airmail. Issued at the dawn of coast-to-coast flight, the C7–C9 series represents a milestone in U.S. postal history and remains a cornerstone for collectors specializing in early airmail, engraved BEP classics, and intact selvage Back-of-Book issues.

This particular plate block retains intense color and clean perforations, with Plate No. 18248 clearly printed in the selvage. Mint multiples this well-preserved are increasingly desirable, especially for collectors focusing on larger plate blocks, aviation-themed issues, and BEP intaglio print varieties. The block displays beautifully on album pages and makes a substantial addition to any advanced airmail or 1920s U.S. philately collection.
