Xero was a key building block in the creation of comics fandom. Produced by Dick and Pat Lupoff with Bhob Stewart (uncredited), it was a widely circulated science fiction fanzine that began to examine comic books thru the pivotal series “All In Color For A Dime.” Those articles help focus the attention of would be comic fans in comic books, and the entire series was later reprinted in book form. Xero went on to win a Hugo, and some of the articles were reprinted many years later in a hardback book. In Flyer #5, the supplement to Xero, Dick Lupoff mentioned that the circulation of the zine was 160 copies. No copies were for sale, and no subscriptions were ever accepted. It was only available by direct mailing with recipients getting one free first time copy, and you only got subsequent issues by trading your zine for it, or writing letters of comment (long letters, not just post cards and thank you notes), or writing articles for the publication. 38 pgs, mimeographed on twiltone paper, side-stapled. Contents include:
