Besides the 1893 Columbian Issue, the only other commemorative stamps issued during the nineteenth century came about when Edward Rosewater, publisher of the Omaha Daily Bee, convinced Postmaster General James A. Gary to issue a set of nine stamps to commemorate the 1898 Trans-Mississippi Exposition being held in Omaha to promote development of the Midwest and West.
Surprisingly, the designs of the Trans-Mississippi stamps have no explicit connection to the Exposition. Unlike the Columbians, they don’t bear dates, and the illustrations on each stamp bear only the caption of the painting or photograph used, without obvious relationship to the others. All the values from one-cent to two-dollars were printed from plates of one hundred subjects and were printed on double-line watermarked paper.
