To mark the centennial of Oklahoma's statehood, the United States Postal Service issued this commemorative stamp on January 11, 2007, in Oklahoma City. The stamp features a painting by Oklahoma artist Mike Larsen, a member of the Chickasaw Nation. The artwork depicts a serene and colorful sunrise over a river, reflecting the state's stunning landscapes. The design also incorporates the famous opening line from the title song of the Rodgers and Hammerstein musical "Oklahoma!," "Oh, what a beautiful mornin'..." This not only pays homage to a cultural touchstone but also evokes a sense of optimism and new beginnings, fitting for a centennial celebration. The musical, which debuted in 1943, has had a profound impact on the state's identity, and its title song is the official state song. This stamp beautifully merges Oklahoma's natural splendor with its cultural heritage, presenting a picturesque and evocative tribute to the Sooner State.
