I have just finished reading Volumes 15 and 16 and will buy more when I can afford them. I do know that his best period was said to be the two or three years after World War II and that is what I am concentrating on now. The books read like a film noir movie with a touch of William Powell, Robert Mitchum, Batman, and the Bowery Boys. The stories are still fresh today and the art is excellent. You can see the influence Eisner had on MAD, DC and Marvel. Unfortunately The Spirit was not available by the time I was teaching as I would, have used the series, as I did various other comics, in the classroom. The Spirit is sort of The Lone Ranger, though why the mask was needed no one knows despite the explanation that the first publisher wanted it. Only the inspector and his lovely daughter, clearly modeled after Betty Grable, and Ebony know who he is for sure. Some may think that a black kid as a side kick named Ebony is racist, but for the 1940's this was pretty advanced. Ebony himself deserved a comic strip and he is a true right hand man for The Spirit. They've made movies of The Saint (plus TV series), radio's The Shadow, and all kinds of comic heroes. The Spirit would seem the most logical one to be made into a film as it already has everything there.
