A few years ago we featured WPA posters about books and reading, but the WPA produced posters on a wide variety of themes many with strong kid-appeal both in content and colorful, graphic style. See some we've picked out below the jump.
We started our browsing at a posters, prints and maps website called Rainfall that has a slew of WPA posters in a variety of sizes. For example, the Keep Your Teeth Clean poster above comes in 8.5x11 for $8 or 11x14 for $12.
eBay is another good source for reproduction WPA posters. eBay store, Zazzle, is a place to start and they even print some on canvas.
