The 1940 Coronado Expedition stamp commemorates the 400th anniversary of Francisco Vasquez de Coronado’s two-year exploration of the American Southwest. The stamp features a reproduction of Gerald Cassidy’s painting, Coronado and His Captains. The top right corner of the stamp features the Coronado coat of arms. This was the last postage stamp issued under Postmaster General James A. Farley (famous for his role in the Farley’s Follies). He resigned because he disagreed with President Roosevelt’s decision to run for an unprecedented third term.
