Picked up a small lot of random stuff from a nearby bookstore owner this weekend. Contained a handful of decent stuff - later printings of Blackmoor, Swords & Spells, Chainmail and a bunch of early Dragons. Some of it isn't in the best shape, but the price was right.

The lot also had the following:

Tri-Tac Systems - FTL: 2448 (Green Plastic 3-ring binder, 102 pages, 1982 with Errata sheet)
CWA CON 1981 Program Guide - July 16 - 19, 1981 (Northlake, IL)
CWA CON 1982 Program Guide (Northlake, IL)
MDG MichCon 10 Gamefest Newsprint Program Guide - June 12 - 14, 1981 (Oakland University - Rochester, MI)

Any ideas about value? I'd imagine old convention program guides don't have a very large audience, but they are fun to flip through.
