I'm not sure if this is the proper forum but it seems best.
I recently found someone online in possession of two items of oldschool Zork memorabilia and he's willing to part with them if I make him a fair offer.
After scouring the internet I can't find anything even approaching a price or a resale value for these items, and I don't want to insult him or anything like that, so a google search for people who know Zork led me here where I can ask you for your opinion even though you don't know me yet.
One is a Zork I poster by David Ardito
The other is a Zork II poster by some italian artist.
If it is inappropriate to ask a question like this here, I apologize and will be on my way, but if anyone out there knows what I should do, please let me know. He seems convinced that they're ultra-rare and my inability to find any information about them doesn't help.
