I don't usually look at Discogs. However I took a look today and noticed this
https://www.discogs.com/sell/item/930819735
The picture sleeve shown for sale must be a photocopy, because I own the original sleeve with those exact autographs.
Anyway, it's the yellow vinyl pressing which never had a picture sleeve.
edit - oh I see how it works. The data (including sleeve picture) is from the discogs database, not provided by the seller. Obviously that system is not ideal, and can be very misleading for a potential buyer.
