Old Cram's Atlas Map ~ GIANT Pennsylvania MAP approx. 40" X 49" ~ Folded ~.  colorized and shows early power lines. I am assuming this may have hung in a high school or possibly a county courthouse.  Would make a fabulous piece to be framed.  It has been folded and has damage at the folds although it is all in one piece.  You probably won't see another one like this.  Feel free to send me an offer.
