Scott #C20 #C21 #C22 – 1935 "Globe and Airplanes" Airmail – Curated Mint Blocks of Four

This curated set features the complete trio of high-denomination 1935 “Globe and Airplanes” airmail issues: Scott #C20 (20¢ Green), Scott #C21 (25¢ Blue), and Scott #C22 (50¢ Rose). Each block of four is mint and well-preserved, representing one of the most visually striking and historically significant U.S. Air Post designs of the 1930s. Issued to handle long-distance and Transpacific airmail rates, this series reflects a pivotal moment in early aviation and the evolution of global postal networks.

The blocks display the engraved aircraft, radiating lines, and detailed globe motif that define the set, with the strong color impressions typical of mid-Depression BEP intaglio work. Mint multiples of C20–C22 remain popular with collectors of classic U.S. airmail issues, high-denomination Back-of-Book material, early aviation themes, and pre-war postal history. These blocks are offered as mint examples; specifics regarding centering, gum, and margins can be provided upon request.
