Does anyone remember which of the CTW Magazines had a regular contest in which they printed a cartoon with blank balloons and you could send in your ideas of what the characters depicted should be saying? It was one of the three, but I can't remember which one and I'm on a quest to find the issue that my idea was printed when I was 4 or 5. That said, if someone knows and actually has back copies, I'm looking for a cartoon of two astronauts standing on a planet shaped like a giant hexnut. Any help would be greatly appreciated!
