Now- All Together. The U.S. Treasury commissioned this poster, printed in 1945, to promote the 7th War Loan Campaign. The artist, C.C. Beall (1892-1967) shows the raising of the flag by U.S. Marines on Mt. Suribachi on Iwo Jima.

I have many other vintage World War I and World War II postcards listed. These are not from that era I don't think but only depictions of posters from that era They don't look that old although they may be. They are in excellent condition.
