Old collectible magazines:
Cosmic Search. First 13 issues (that's all they published, beginning Jan. 1979). Includes articles by Philip Morrison, Frank Drake, Arthur C. Clarke, Jocelyn Bell Burnell, Carl Sagan, Jay Psachoff, B.M. Oliver, Virginia Trimble, John Kraus and many other SETI pioneers.
AstroSearch. First 4 issues. (Cosmic Search evolved into AstroSearch, so they're the "same" magazine. Starting in 1983. I'm not sure if it ended after these 4 issues).
SETI Quest. First 4 issues, plus one from the second year. Starting in 1994.
Amateur Astronomy. First 8 issues. Starting in spring 1994.
PLUS: Guy Ottewell's Astronomical Calendar: 1995, 1996, 1998, 2000.
Everything is in really good condition. No tears, no writing. Some of the AstroSearch mags have yellowed.
I will accept the best reasonable offer I receive by Thanksgiving.
Checks, m.o. okay.
