just noticed that the listing says the signed art card is packaged in a jewel case cd on top of the booklet but in the video, he is signing prints way too big to package in the case, and signed vinyl is not offered so I'm not sure what that's about.
It looks like what he is signing are the album-sized prints for the vinyls which are popping up in all the Indie stores, here are a couple but it's probably in all of them
