The Central Overland California & Pikes Peak Express Company was organized in February 1860 and operated a stage and express route over the Central Route. By August 1860, when this cover was mailed, the company was in financial trouble, but it launched the Pony Express on August 3 -- to some degree as a publicity-generating venture -- with the hope of securing lucrative government contracts. This cover, addressed to an employee of the company at Salt Lake City, was apparently carried by one of the regular stages leaving St. Joseph, which would have travelled via Julesburgh (Colorado) and Fort Bridger (Utah). There is no indication of an express fee.

stampEXTREMELY FINE STAMP ON AN EXHIBIT-WORTHY DOMESTIC COVER. THIS IS THE "FILSTRUP" COVER, ONE OF SIX RECORDED COVERS BEARING THE 90-CENT 1860 ISSUE. THIS IS THE ONLY DOMESTIC USAGE.
The highest value of the 1851-57 series -- the 90c stamp with a portrait of the youthful George Washington in military uniform -- was issued in 1860 (earliest recorded use is September 11). Its use was limited by the high denomination and the stamp's relatively short life, due to the demonetization of all United States stamps in August 1861, a measure designed to preclude the sale of stamps originating in rebel states' post offices.
This is one of six recorded 90c 1860 covers: 1) Sep. 11, 1860, to Augustine Heard & Co., Shanghai, single franking for double rate, ex Gibson, Hindes and Kapiloff, 2) Nov. 3, 1860, to Barcelona, Spain, ex Caspary, Rust and Kapiloff, 3) Nov. 9, 1860, to Augustine Heard & Co., Shanghai, ex Needham, Paliafito, Ishikawa, Myers, 4) Jan. 8, 1861, single used on legal-size cover from Cincinnati, the cover offered here, ex Filstrup, Grunin, 5) Jul. 16, 1861, to Edwin Howland, Cape of Good Hope, used with 1c pair, 3c, 10c and 30c for four-times 33c rate, ex Jacobs, Newbury, Ishikawa, and 6) Jan. 26, 1861, to Mackellop Stewart & Co., Calcutta, India, used with 12c and 30c, ex Armitage.
