Leaf's other notable creation was the Watchbirds cartoon series, a cartoon commentary on human behavior. It ran as regular feature in the Ladies' Home Journal and was later collected into several books.
During the Second World War, Leaf and Ted Geisel (aka Dr. Seuss) created the pamphlet, This Is Ann, about a mosquito spreading malaria to men who failed to take precautions.
On April 22, 1995, Leaf was inducted into the University of Maryland Alumni Hall of Fame. Some of his books have been brought back into print in recent years.
