This book is out of my father‘s shop and has not been used. There is a price of $.75 written on the cover and very little wear. See all photos before purchasing. Will be mailed media mail. The product is a "Working with Plexiglass" manual published in 1947 by Craftsman in collaboration with Rohm & Haas from Philadelphia, PA. It provides instructions and guidance on using Plexiglass in shop settings. Craftsmen enthusiasts may find this historical manual valuable for learning about working with this material.
