I'm fascinated at the thought of a near-complete set of FSM finding its way all the way down to Guatamala. We're talking about 20+ year old magazines that have lasted way longer than any of the books I worked on at my previous employer!
Anyway, here's the break down of the early issues, straight from the bright red bound 1982-84 volume in my office:
Spring 1982 - "test" issue released in January to see if there was a market for such a magazine. There was, so....
Fall 1982 was the "charter issue," Vol. 1, No. 1, of the new quarterly magazine, followed by....
Winter 1982
Spring 1983
Summer 1983
Fall 1983
January/February 1984, at which point FSM became bi-monthly.
