UPDATE: Looks like this book is only selling for $50 to $60 now.
No more $100 sales. 

So this week Marvel released an unannounced Eminem variant showing Eminem hanging out with Iron Man in 8 mile.

Its stupid, its funny, its the ultimate cheese of all cheese variants.

As of right now there are three ebay auctions (one ended) that are past the $100 mark. This book was reported as a “one per retailer” with many retailers getting at least two. Easy Flip if you can find a copy for $50 or less – (I found 5 all ranging from $10 to $40)
