George W. Bush offered some solid advice to aspiring artists during an interview with CNN over the weekend: “Never paint your wife or mother.” The former U.S. president-cum-painter, whose paintings include self-portraits, family members and Russian President Vladimir Putin, among other world leaders, appeared on the program to discuss his new book about his father titled “41: A Portrait of My Father.” The book cover includes a portrait of George H.W. Bush painted by his son.
