Hi, I need help figuring out what this is a picture of. I got a bunch of older books from a garage sale and found this printed picture folded up in the pages of a 1948 Audels Diesel Engine Manual. Other books were of religious materials from 1880 and up. Most were of print in New York-I live in Rochester, NY. There is no writing on the paper it is printed on at all.
I've called around museums and the library and have yet to get answers.
