@Mbitr, thanks for the suggestion but that sub-forum appears to be more of a marketplace. I'm just trying to see if anyone has any ideas regarding this image.
I have seen threads on the Collectibles section which are neither buying and selling nor auction, so I guess you can try raising this one there. If this piece of art is something worth collecting and has value more than its face value, someone might have already come across this and knows a thing or two. The Collectibles section has a lot of experts on Bitcoin-related artifacts.
Does the photo have a sign or some sort of scribble at the back?
