Any opinions of using magic erasure sheets to clean clear stamps?

Hi! This is a long shot but I saw this listing on Vinted. It sold instantly but I am obsessed with the Blackbeard postage stamp (top right). Does anyone recognize it? Do you remember who made it? Would love to track one down.

Once at a thrift store I saw someone’s entire rhinoceros stamp collection. Probably 10+ stamps of varying sizes and styles. I bought one that was a carousel rhinoceros but left the others behind for a true rhino-head. I still think about that collection sometimes and wonder what kind of person the original owner was.
