Not really...when FS sold their "signed/limited" version of 'Best American Short Stories,' they actually rebound the book, so it was a totally new version.
If TOR/Gauntet had rebound the book, and bound in the signature sheet, then I'd be impressed...although they never claimed that, so it wasn't like they were lying or anything.
It did say "tipped in" but I always get confused with those terms...all it means is "included with."
