September 1850 and June 1852 on mail handled by route agents aboard ships
of the Pacific Mail Steam Ship Company, while contract mail carried by PMSS
Co. was received in locked bags, letters picked up en route were presumably
postmarked by official route agents on board, as evidenced by approximately
25 known examples of the rare route agent markings on covers (Image Magnifier) |
