It's Cambria County Pennsylvania which is mostly small towns with a large fold out map of Johnstown Pennsylvania. I have links to an Adobe PDF file of the CSP booklet itself and separate links to an image file of the Johnstown map and an Adobe PDF file of the Johnstown map. Date on this CSP is January, 1969.
