No, not George Eastman, but E. R. Eastman.
I don't know who he was, but this gem,
Another Batch of Eastman's Chestnuts,
is a collection of funny stories "stolen and edited by E. R. Eastman." (He wrote that "stolen" part, not I.) This book is 124 pages of fun for $1.50. Look for it is the glass case, and enjoy.
