This 4-cent stamp commemorating the 50th anniversary of Arizona statehood was issued on February 14, 1962, through the Phoenix, Arizona, post office. Designed by Jimmie E. Ihms and James M. Chemi, the stamp's central subject is the flowering arm of a giant saguaro cactus, the bearer of the beautiful Arizona state flower. A full-grown saguaro is silhouetted in the foreground, with the moon behind a cloudbank reflected on the valley below to create a desert night scene.
The stamp was printed on the Giori press and issued in panes of fifty stamps each. An initial printing of 100 million stamps was authorized.
