5c Franklin illegal use from Arkansas Territory to Washington, DC on cover

Peter P. Pitchlynn, Native American (Choctaw), born 1806 · July 14, 1854

This is the only cover from Eagletown prepaid with an 1847 postage stamp. It was addressed to Col. P. P. Pitchlynn, a Choctaw chief, while he was in the "City of Washington." Although Eagletown was in unorganized territory west of the Arkansas border, it was attached to Arkansas in the Post Office Department records for administrative purposes, and hence the designation "Ark" in the townmark.
