The campaign map I've been busy producing with Hexographer is, as I'm sure most people know, based on the map from Avalon Hill's Outdoor Survival game. Over the course of play, I've changed details from the original to suit the direction of the campaign, but its basic appearance is still recognizably that of Outdoor Survival.
Anyway, when I cracked open my ancient copy of Outdoor Survival, I found a copy of interesting Avalon Hill artifacts: a fold-up order form and a registration card. Both are actually quite fascinating windows on both the world and the hobby of 30 years ago.
Greetings & Readings (then located in Towson, Maryland) and getting a lot of RPG stuff there that I couldn't find anywhere else, like the Grenadier Gamma World miniatures. Also of interest is the reference to "Military Outlet." As I've said before, we can't underestimate the huge role military personnel played on the early hobby.
