Issued on June 14, 1957, in Oklahoma City, this 3-cent stamp marked the 50th anniversary of Oklahoma's admission to the Union on November 16, 1907. The stamp's design is a powerful and concise representation of Oklahoma's historical narrative. The phrase "Arrows to Atoms" encapsulates the state's rapid transformation over its first half-century. The arrow represents the deep-rooted history of the Native American tribes, particularly the Five Civilized Tribes who were relocated to what was then Indian Territory. It also evokes the imagery of the American frontier and the "Sooner" spirit of the Land Rushes. The atomic symbol, a potent emblem of the 1950s, signifies Oklahoma's embrace of science, technology, and modernity. The state was home to important developments in the energy sector and was looking towards a future of progress and innovation. The stamp's deep blue color provides a stark and serious backdrop for these contrasting yet connected symbols, all superimposed over a map of the state.
