Hollywood: The Tangents Group, 1965. Magazine. 32p., including covers, 5.5x8.5 inches, story, articles, reviews, very good digest magazine in stapled pictorial wraps, mild rusting to staples, stamp on cover of Society for Individual Rights in SF.
Debut of Tangents which was Slater's and Billy Glover's new project after the acrimonious split from One Magazine (itself a spin-off from Mattachine Society Review) which ran monthly and/or bimonthly from 1965 to 1970. Co-founded by mystery writer Joseph Hansen. Tangents had been a column in One Magazine and when the split happened Slater attempted to cull the subscriber list by sending fliers with the change of address pointing to his new offices. This first issue prints an editorial that refers to One Magazine and the letters in the back are addressed to and relate to One.
