You have to love US government food posters, especially of the “Be Patriotic!” or “Let the Hen Whip the Kaiser!” or “Can All You Can—It’s a real war job!” varieties. For more, you can check out the National Library of Medicine’s exhibit of food posters from World Wars I and II.  Many of these can be seen online at the Smithsonian’s site.  The exhibit was curated by Cory Bernat.

Enjoy!
