The first printing has a large (magazine size) booklet, as well as runes on the counters, while the later prints in ziplock have a digest-size (legal-size paper folded over) booklet, along with drawings on the counters. (All the maps say 1975.)

Most data I have seen claim that two versions of the digest-size edition exist, so if you have this, it could be either 2nd or 3rd edition. Someone else might know how to distinguish 2nd from 3rd.

Regarding appraisal, prices for retro-gaming items have shot up so much in recent years that all I can say is that it once was worth $100.

Thank you, guys - No printing statement inside the booklet, but it is the legal sized folded booklet (digest) - so Im looking at 2 or 3 - many t hanks, guys.
