Here is the response from CGC:
Hello Steve,
Thank you for your email. Celebrity Authentics requires that any books signed in partnership with them be stickered with a secondary hologram, which they provide, however, CGC must wait until all of the books from the signing have been graded and encapsulated before Celebrity Authentics will provide the hologram stickers to CGC. Unfortunately, this at times causes an additional delay when comes to celebrity signing in partnership with Celebrity Authentics. We apologize for any inconvenience that you have experienced. Regarding the books you have seen on eBay, these books were sent out in error and are being returned for correction.
