Works Progress Administration posters

I love the design of this vintage anti-vandalism poster. (Click on it for a larger image.) According to this site, it was part of a series printed after WWII by the Works Progress Administration. Here's more on the WPA Posters from the Library of Congress's "By the People, For the People" exhibit:
result"The By the People, For the People: Posters from the WPA, 1936-1943 collection consists of 908 boldly colored and graphically diverse original posters produced from 1936 to 1943 as part of Franklin Delano Roosevelt's New Deal. Of the 2,000 WPA posters known to exist, the Library of Congress's collection of more than 900 is the largest. These striking silkscreen, lithograph, and woodcut posters were designed to publicize health and safety programs; cultural programs including art exhibitions, theatrical, and musical performances; travel and tourism; educational programs; and community activities in seventeen states and the District of Columbia. The posters were made possible by one of the first U.S. Government programs to support the arts and were added to the Library's holdings in the 1940s."
A reprint of this Result poster is on eBay right now, but of course I'd rather have an original. Link (Thanks, Michael-Anne!)
