Robert Osborn was a prolific WWII cartoonist at age 40. His work in posters and booklets is very collectible. In the lot of 62, six are 10"w x 12.5"h and 56 are the reverse, 12.5"w x 10"h. All are on heavy card stock with two holes punched at the top for a binder or hanging. There are no duplicates and the numbers printed in the lower left corner run from 289 to 382. Condition is generally very good but someone trimmed 1/2" off the right margin of the 56 which cuts part of the USN wing logo in the lower right corner but does not affect the wonderful images. I have priced these very reasonably at less than $3 each for the entire lot of 62.
