I do like some of your pepe cards, I'm taking copies for my own collection, you can't really prevent people making exact copies of your digital assets, that's a big impediment to digital items becoming collectibles. You can't prevent me enjoying your digital property anymore than Hollywood can, my pepe cards look exactly the same as your ones do! I don't need to 'own' them to enjoy them just as much as you do, so why would I ever buy them from you ?
Is there a block explorer for these pepe cards, can I check a wallet address and see all the images in that wallet? By definition anything digital can be copied, so how are they rare exactly?
Because, math and stuff... each card is a Counterparty asset (embedded into the Bitcoin blockchain).
Sure, you could save the image itself to your computer, but that doesn't mean you own the card.

Blockscan.com is one of the Counterparty explorers.
