William McKinley of Ohio (1843-1901), the president of the United States who lead the nation during the Spanish-American War and who was felled by an assassin at the Pan-American Exposition in Buffalo, New York, appears on the 7-cent stamp. It was McKinley’s second appearance on a stamp. He first appeared on the 5-cent stamp in the Louisiana Purchase Exposition Issue.
Clair Aubrey Huston designed the 7-cent McKinley stamp. The vignette, inspired by George Rockwood's 1898 photograph of the president, was engraved by Louis Schofield. The frame was engraved by Edward E. Myers, Edward M. Hall, and Joachim C. Benzing.
The flat plate sheet stamp was issued on May 1, 1923, both in Washington, D.C., and McKinley’s birthplace, Niles, Ohio. The stamp was subsequently printed on the Stickney rotary press.
