The poor thing was obviously "stan-lee'd".
That kinda accounts for the 2500 imho.
, not a fan of the signature series?
Yes, it would appear that a signature increases the value of an otherwise worthless common drek book.
When it comes to a true vintage collectible comic book, however, a signature is probably treated more like a clear and visual defect by the marketplace.
Probably one of the reasons why the signed 8.5 copy of AF 15 in the most recent HA auction managed to sell for only something like more than a $35K discount to the condition guide price.
This is the book you speak of:

The signature isn't visible. I don't think having a signature impacted the value of this book.
I'm thinking it is the condition of the book and the fact it is CBCS.
If this book was cgc 8.5, SS, it would have done much better.
