I once read about an Idea Board that Mr. Pinkwater wrote about. It was an actual bulletin board where you could either leave an idea or take one. I used his idea outside my room in an elementary school I taught at many years ago. It was a great success. I am trying to remember the details of the article/story/essay. Hope someone can help.
You're telling about the E. J. Sperry Thought Factory that existed for a while in Chicago. It was an old house with a couple of bulletin boards on the iron fence. It figures in my extremely good novel, Bushman Lives! for a page or two.
