Today's vintage children's book, Leonard Discovers Africa, is part of The Time Machine Series. I'm not familar with the illustrator, Barbara Robinson, but I like her work. Other books in the series are: Leonard Visits Space, Leonard Visits the Ocean Floor, Leonard Discovers America, Leonard Visits Dinosaur Land, Leonard Visits Sitting Bull, Leonard Goes to the Olympics and Leonard Equals Einstein.
