Great double page map of Pennsylvania divided into counties. Shows towns, major routes and waterways. In excellent condition with a few small tears. After serving in the Union army, George F. Cram (1842-1928) joined his uncle's map business and later established his own engraving and publishing firm in Chicago in 1869. This is an excellent example of his color lithography.
