A 3-cent stamp commemorating the 50th anniversary of Oklahoma statehood was issued in Oklahoma City, Oklahoma, on June 14, 1957. This special stamp was first placed on sale on the opening day of the Oklahoma Semi-Centennial Exposition.
Designed by William K. Schrage, the stamp shows a horizontal arrow superimposed on a solid outline map of the state of Oklahoma and piercing the orbital emblem, which has become symbolic of atomic energy. The arrow represents the frontier days of Oklahoma prior to statehood in 1907, and the atomic symbol represents the new frontiers. Across the top of the stamp is the wording "1907 Arrows to Atoms 1957," and across the bottom "3c United States Postage" in dark Gothic. Arranged in five lines within the right half of the state boundaries is the wording "50th anniversary of Oklahoma Statehood" in whiteface Gothic.
The stamp is 0.84 by 1.44 inches in dimension, arranged horizontally, printed by the rotary process, electric-eye perforated, and issued in sheets of fifty. The color of the stamp is blue. The printing of eighty million stamps was authorized.
