Picture kept by Peeragon
Minted on Peeragon before it wrote pictures to the chain: the deck and card are on Peercoin, the picture is on Peeragon.
Any PeerAssets software reads the same deck and cards from the chain: look up the deck's transaction, then every transaction paying its tag address. We follow pypeerassets, PeerAssets' reference implementation, and PeerAssets Media for one-of-one decks.
