Fanzine's were amateur magazines written by fans. Alter Ego was one such, Star Studded Comics by the Texas Trio is another (I just recently finished my run of SSC). There's a really great book you should check out called "The Golden Age of Comic Book Fandom" by Bill Schelly. Great reading!
One of the things that made Fanzine's interesting, besides the articles on comics & characters, was the original strips written and drawn by the fans of these publications, some of whom went on to professional careers in comics.
I'll post some scans shortly.....
