The Department issued this 4-cent stamp to commemorate the centennial anniversary of Oregon statehood through the Astoria, Oregon, post office on February 14, 1959. The stamp's central subject is an unhorsed covered wagon, typical of those used over the Oregon Trail by pioneers, with Mount Hood to the right. The terrain slopes to the left (to the west), meeting the Pacific Ocean. In the upper portion of the design, in dark Gothic lettering arranged in two lines, is the text "Oregon Statehood 1859 — 1959." In the sky, to the wagon's left, is a white star, symbolizing statehood, while across the bottom in white Gothic lettering against a solid background is "US Postage 4-cents."
Designed by Robert Hallock, the stamp was printed by the rotary process, electric-eye perforated, and issued in panes of fifty stamps each. An initial printing of 120 million stamps was authorized.
