It was created in 1918 and there were two versions, with and without an address on the bottom.
My paper guy Jaime did a marvelous job on the piece. He de acidified it, took out a few wrinkles and linen backed it. Looks pristine now.
James Montgomery Flagg (1877-1960) is perhaps most famous for his iconic Uncle Sam poster. He was also known, among other things, for his wonderful illustrations for Harper's Weekly.
This poster is ready to frame. If you know a former marine who might be interested let them know that I have it.
