So when I saw this box on the very top shelf, I knew I'd regret it if I didn't snag the item right then and there:
|That white blotch is a reflection from the camera flash, not part of the box art.|
Oh, and the best part: The particular store I was in had just moved to a new location, and everything was for sale at a 50 percent discount--on top of the usual half off. So I paid nine bucks and change for a first edition Gamma World rulebook and box. Definitely a fruitful treasure hunt!
