Jones & Russell's Pike's Peak Express & Co. Handstamp April 12, 1860, Denver City, with Two #26 3c Dull Red Singles Tied by "Leavenworth City, K.T" Datestamp, on 1860 Cover to Missouri

The cover originating in Leavenworth City, Kansas Territory with "Denver City APR 12 1860" circular company handstamp, addressed to Saint Louis, Missouri. The left stamp with a piece missing in left margin.

After Russell, Majors & Waddell (RMW) assumed control of the Leavenworth & Pike’s Peak Express on October 28, 1859, operations continued under the name Jones & Russell’s Pike’s Peak Express Co. until its absorption by the Central Overland California & Pike’s Peak Express Company (COC&PP) in February 1860.

Despite the transition, Denver continued using Jones & Russell markings into June of 1860, making this April 12, 1860 usage a scarce and desirable example from the short-lived RMW period, just days before the COC&PP began the transcontinental Pony Express in April 1860.
