When I was English class in either the 7th or 8th grade, my English teacher told the class that there was a famous artist who drew pictures on the backs of his checks. The famous artist drew pictures on the backs of his checks because he thought (correctly, according to my teacher) that people would tend not to cash the checks in order to have a picture drawn by this famous artist. I don't remember who this artist was. Is someone going to ask me "what does it matter?" I'm curious about who it was. That's why it matters to me. What famous artist drew pictures on the backs of the checks that he wrote?
