Do we know for sure if he painted with his right or left hand? A self-portrait I saw yesterday makes me wonder.
I have no cites or proof but I think I read it in Readers Digest years ago that he was ambidextrous.
ETA I just googled it. It says he was ambidextrous. Dyslexic and paranoid. Jeez, what a combo.
That confirms my contention that the painting that I saw was done with his left hand. Looking at several of his self-portraits, I think ambidextrous is the best guess.
