1898 Trans Mississippi
ABOUT THIS SERIES
The Columbian stamps had served their purpose so well that the Postal Department, it seems, was anxious to repeat the experiment of issuing a commemorative set at the first suitable opportunity. The chance came in 1898 when the promoters of the TransMississippi Exposition of Omaha petitioned the authorities to provide an issue to advertise their exhibition. When it became known to philatelists that some new Omaha picture stamps were under consideration, they caused a great outcry but no heed was taken of their protests in official quarters and the series was duly received in the month of June.
