My original AD&D DM screen was damaged in the leaky pipe incident that took most of my original books, that is the portion with the dragon and the fighter, the other tri-fold is okay.
I found one guy on e-bay selling each tri-fold separately for $25.00. I found another that appears to be selling both tri-folds for a little more, so I went with that one.
I had been planning to do this, but with the news of the passing of Dave Trampier, I am sure anything with his artwork will see a spike in price.
I hope I am not disappointed.
If his family ever decide to put out a new screen with his art, I will buy it!
