Ferdinand the Bull, Reluctant Culture Warrior As the gentle giant who just wanted to live his best life turns 90, Munro Leaf and Robert Lawson’s classic fable is as apt as ever. “He had a favorite spot out in the pasture under a cork tree. It was his favorite tree and he would sit in its shade all day.”Credit...The Morgan Library & Museum, 1970.16:1-37, Gift of the Mary Flagler Cary Charitable Trust. Used by permission PRH LLC.
