I was not aware of this forum until recently! I've been having a clearout and recently sold a collection 12 issues of The Beholder including all 4 issues of The New Beholder. Perhaps I underpriced them
. The day after I shipped them, I found a copy of issue 25, which I think is the final issue I have, and is the last issue by the original creators. It goes live on eBay tonight, if anyone's interested. I plan to list some issues of Player's Association News (TSR UK) from 1981 as well, if that floats your boat...
