Genuine-use 1902 cover mailed from Hudson, New York (July 27, 1902) to Mr. Edward Gaul Rusk, 2000 E. Baltimore Street, Baltimore, Maryland, bearing a 2¢ stamp with Hudson town cancel on front. Back carries a bold New York & Washington R.P.O. Train 31 transit backstamp dated July 1902, Baltimore, MD — documenting the full routing. Some front staining and light edge wear; both cancels clear and legible. A solid early RPO transit piece with point-to-point documentation.
