looks like Lil Abner to me. I haven't seen this design talked about anywhere. But I did find this article about feedsacks posted on Etsy. And the Quilt History site has a very informative article on feedsacks.
When I saw this quilt on a trip summer 2010 in California, I just had to buy it. It is four feedsacks sewn together to form the center panel.
The back of the quilt is also feedsacks sewn together. A large pink and red flower design.
It is Kent's Cloth of the United Nations. The fabric was printed in 1942 by Percy Kent of buffalo New York. Using famous WWII battles and Alliance symbols including Tojo, Hitler and Mussolini.
