Vintage 1931 Smooth-On Handbook

A vintage, 1931 Smooth-On Handbook. The paperback booklet exterior is in rough condition, but is so interesting I'm offering it here. The Smooth-On Handbook is the twenty-second edition(!) and has cool graphics and photographs. The stapled booklet features 136 pages including the index and the interior pages are in good vintage condition with discoloration and minor staining. The exterior cover is torn in the front and someone has written all over the front cover, I believe if I'm translating the handwriting correctly, explaining how they used the product to make a repair.

The booklet measures approximately 7 1/4" x 4 1/2" wide. The Smooth-On Company is still in business, what an admirable feat!
