The 25-cent Idaho Statehood commemorative stamp went on sale January 6, 1990, in Boise, Idaho. Idaho was admitted as the forty-third state on July 3, 1890. The stamp features the state bird, the Mountain Bluebird, perched atop a rustic fencepost, against a backdrop of blue sky and the rugged peaks of the Sawtooth Mountain Range.
Designed by John Dawson, the stamps were produced by the photogravure process by the American Bank Note Company in panes of fifty.
