I agree that it will sell for what it sells for... but I've always had difficulty accepting this notion, at least in my own collecting of something being 'as good as it gets except for the 10 others locked up elsewhere' sort of situation. I.e. If I'm at a restaurant and I want a steak and am willing to pay $30 for it, but all they have is chicken which is normally $15, I'm not paying $30 for the chicken because its 'as good as it gets' on the menu. Its still chicken. It didn't magically turn into steak because there is no steak to buy.
Reading through this thread my gut reaction seems about right. this is a cool, but weird piece. Late in the run, two boards... who knows what it will sell for. Of course, that's the fun of this kind of thing.
