It was intended to print the Trans-Mississippi issue with a black vignette and a frame in color. The bi-color idea had to be abandoned because of the fact that the Spanish American War, which broke out in April, 1898, necessitated the printing of enormous quantities of revenue stamps and the facilities of the Bureau were taxed to the utmost . The time and manpower needed for the printing of stamps in two colors could not be spared and it was necessary for the Bureau to abandon the proposed bi-color stamps in favor of stamps of single colors.

For the vignette was based on a painting by William Lamprecht called "Father Marquette and the Indians"

Marquette and Jolliet did not discover the Mississippi. Indians had been using it for thousands of years, and Spanish explorer Hernan De Soto had crossed it more than a century before them. They did confirm, however, that it was possible to travel from the Great Lakes all the way to the Gulf of Mexico by water, that the native peoples who lived along the route were generally friendly, and that the natural resources of the lands in between were extraordinary. Equipped with this information, French officials led by the explorer LaSalle would erect a 4,000-mile network of trading posts to systematically exploit those riches over the next century and a half.
