Torbjörn gave me a link in Comments to Tom Leher’s website. He was incredibly talented. Maybe I like him because he was a mathematician. My undergraduate degree was math. If you’ve never heard him go here. His Poisoning Pigeons in the Park takes me back to Don Martin. I had a subscription to Mad Magazine when I was 13. I had the subscription because of Don Martin. I was a real fanboy. Many years later he was testifying in Washington about how publishers take the rights away from cartoonists. William Gaines of Mad was about as bad as they come in that regard. Well, I met Don, and guess what. He was a fan of U No Hoo. We became friends. He died a few years later of Leukemia. So sad to see him pass on.
If you can find it, my favorite Don Martin cartoon story was the guy feeding pigeons in the park. It was probably 1955 or 1956. I read it over and over.
