Advertising text at upper right offers other maps of Philadelphia by the company including a wall map (42" x 36" for $1.50) and a City Guide with map and directory for 25 cents. The map is copyright 1871 by the National Railway Publication Company. The map folds into original embossed and gilt-stamped purple cloth covers. A most uncommon pocket map by a little known publisher.
