We highly recommend two books about Gil Kane, both compiled by a perceptive gent named Daniel Herman. Gil Kane: The Art of the Comics features history and analysis. Gil Kane: Art and Interviews features conversations that helped inform the first book. And both feature a lot of wonderful artwork by one of the great comic book illustrators of all time. Note that I am recommending both books. Like love and marriage, you can't have one without the other. (Well, you can. Dealers like Bud Plant will sell you either one or both. But you shouldn't get just one of them. Between the two volumes, you get a good portrait of a fascinating artist and an erudite, wise gentleman.)
