This is according to Bonnie Floor, a Georgia artist who tells Fox 5 Atlanta that she spent a month in Boca Raton teaching the president to paint:
"He started off painting dogs. I think he said he painted 50 dogs," Flood said. "He pulled out this canvas and started painting dogs and I thought, 'Oh my God, I don't paint dogs!"
He has since turned, Flood says, to landscapes. (And also, obviously: the shower nudes.) "He's going to go down in the history books as a great artist," Flood tells Fox.
