Diane Dillon, American illustrator

Leo Dillon and Diane Dillon were American illustrators of children's books and adult paperback book and magazine covers. One obituary of Leo called the work of the husband-and-wife team "a seamless amalgam of both their hands". In more than 50 years, they created more than 100 speculative fiction book and magazine covers together as well as much interior artwork. Essentially all of their work in that field was joint.
