One of my all-time favorite painters is Wayne Thiebaud. Mr. Thiebaud's oeuvre (big word alert) includes a wide variety of subject matter, especially.... PIE.
"It started out just as a sort of crazy problem to set for myself to orchestrate abstract elements with the subject matter. As soon as I did that, as I say, I couldn't help but look at it and laugh, 'That certainly has to be the end of me as a serious painter--a slice of pie.' But I couldn't leave it alone...It just seemed to be the most genuine thing which I had done." - Wayne Thiebaud
