One of 5 issues of The Magazine of Fantasy & Science Fiction that contain the original appearances of the novelettes that make up Stephen King's 1982 fix-up novel The Gunslinger. (If you don't like the term "fix-up," call it a collection of related stories.)

Those 5 issues are October 1978, April 1980, February 1981, July 1981 and November 1981. A complete set goes for a very good price on eBay - all of these are in excellent condition (Fine) - much better than a set I sold years ago where the best was near-Fine. This is a clean set, with no marks or writing in any issue; age tanning is mild and uniform.
