The 1898 Trans-Mississippi Stamp Issue

The 1898 Trans-Mississippi issue is a series of nine postage stamps issued at the Omaha World’s Fair to commemorate westward expansion in the United States. This website is home to two philatelic exhibits studying the history and development of these stamps.

The Essays and Proofs of the 1898 Trans-Mississippi Issue is an eight-frame competitive exhibit premiering at the Rocky Mountain Stamp Show 2018.

This exhibit details the development of each stamps’ dies using essays and proofs to create a timeline of how the stamps were designed and engraved. The exhibit features original research and shows several unlisted essays and proofs.

Changing the Subject is a ten-frame non-competitive exhibit that premiered at Indypex 2016. A modified version of the exhibit was featured in the Court of Honor at the APS StampShow 2017.

This exhibit focuses on the history of the stamp issue - from its original conception as exhibition advertising, to the unselected vignette subjects, to the “big switch”, to the issued stamps and beyond. It focuses primarily on the 2¢ and $2 stamps, which went through the biggest changes during development.
