These cards for sale have two properties:
1. Physical artwork
2. Digital non-fungible token on the blockchain.
As the physical artwork there will never be more than 266 R.Merkle's and 200 C.Wright's by Geekoid inc. and this is what the company wrote on the cards. This is a bit confusing because as NFT there will never be more than 10 each of the card. This property makes these much more scarce than it says on the back side.
These cards have "DUO" icon in the top right field (different from simple pioneer cards) and on the back side there is tamper proof holo sticker protecting wallet seed with associated NFT. Just
want to say that both of the cards are 1/10 supply physical NFTs
