I think this is the one that was offered up from the Wambold Auction?
Am I right,
I have a 1st edition, that I purchased off of Amazon, it is a first edition in excellent condition, but it doesnt have the poster of extra papers in it, I paid, $65.00 for this copy.
I have seen these range from $50.00 up to $400.00, it just depends on whatever someone want to ask for their copy, but the real market, I would say,
$130.00 to $200.00
Understand you can buy a Brand new 3rd edition with all the added info, for, $139.95.
Hope this helps a little, but to be honest, the prices on these are all over the map
