Gray, Frank A. “Pennsylvania"

Frank A. Gray.  “Pennsylvania." Philadelphia: O.W. Gray & Son, 1875. 15 1/4 x 24 1/4 (neat lines) plus full borders. Light staining along center fold,  A few scattered spots.  Map is double matted for display.  Else, very good condition.  The firm of O.W. Gray and Son began its publishing around mid-century and produced regional and U.S. atlases up to the 1880s.  This map is typical of their work, and its attractive presentation and interesting detail make it a nice example of late nineteenth century Philadelphia cartography.
