The Caldecott Medal for outstanding children's book illustration is awarded every year to the illustrator who has proven themselves to be at the forefront of what is possible in the world of children's literature. 1965's winner is notable not only because his art style was vivid and unusual, but also because he was inspired almost entirely by his work in another field. Beni Montresor's illustrations, often done in a variety of mediums, were heavily influenced by his work as a set designer for ballet and opera. This lead to illustrations both dynamic and compelling, a clear testament to his love of the dramatic that led to such success in his primary career as a set designer. Today we continue our Caldecott Winning Illustrators series by taking a closer look at Beni Montresor's artwork for the book, May I Bring a Friend?
