Thought I'd post this in case anyone missed Mr. Mitt's post on these awhile back. Evidently these are repros that show up from time to time, but collectors are still paying some substantial coin for them. The listing doesn't make any claims about it being authentic and the seller has 100% positive feedback, but that's a lot of money for a fake. Once again it's "let the buyer beware" on ebay.
