This envelope traveled from San Francisco, California, to A.W. Canfield in New York, New York, in only twelve days during June 1861. The $2 red Wells Fargo stamp paid for the Pony Express service and the oval-shaped blue marking, also created by Wells Fargo, cancels it. To pay for the portion of the delivery service through the U.S. mails, the sender used a Post Office Department 10-cent prepaid envelope. A round, green postmark cancels the postal stationery.
