Recently I've been reading a bunch of old Shadow pulps (courtesy of Rich's collection) and I've become a huge fan of the Shadow! I love the slogan,"The weed of crime bears bitter fruit!" I have come to the conclusion that "Batman" is a rip-off of the Shadow. These books were written in the early 1930's (most of these pictured here are reprints from the '6o's) But Batman didn't come into being until the late 1930's. I don't know enough about the subject really, but the Shadow is a really impressive character!
One thing I found amusing was that these two books have their covers switched. The story "The Crime Cult" should have the illustration from "Hands In The Dark" and vice versa.
Anyway, the Shadow books have been keeping me company on the subway to and from work everyday. I'm going to have to seek out more once I've finished reading these ones.
