An auction on eBay has a listing that includes the following information...

I also have 1 of 2 known Upside down Reversed Cats Error Holograms so on the front the Cat is upside down when it should be face up to the Holiday Series letters. If you want to own 1 of only 2 known Riveria Error holograms out of the 1000 made send me an email with an offer I can't refuse.

Is this considered a legitimate error. Some of you may remember the last time I tried to by a Halloween error chip it didn't work out too smoothly

Thanks for any advice!
