Today's vintage children's book is They Didn't Use Their Heads, written and illustrated by Jo Ann Stover. This mid century picture book uses humor and examples to get kids to think about their behavior. Nice pen and ink illustrations by Stover and I like the crayon treatment for the cover. I wasn't able to find much information about Stover who passed away in 2009, but I did find a nice article in which her daughter was interviewed. You can read that here.
