In no particular order, except for the first on the list, these are books that are related to my own art that I have especially enjoyed and that have greatly inspired me. My illustrator uncle and role model Eldridge King gave me the Gene Byrne book when I was just a kid. It had more to do with my becoming an artist than any other single book.
