"I received these from a trustworthy showbiz representative. They wore these during a photo shoot, then signed them afterwards."
"These haven't gone to the laundry, so please bid only when you can accept these terms."
Some comments on fan sites:
"The seller should at least mention the name of the magazine and the date of the photoshoot."
"How can people fall for this?"
"Scary."
* As of this writing, both auctions have ended and the seller has deleted his account.
