Curio Cards is an online art show and permanent gallery that launched on May 9, 2017. Curio is the first Art NFT project on Ethereum, featuring 30 unique series of cards from 7 different artists. Curio Cards are referenced with CryptoPunks and CryptoKitties in the original ERC-721 Non-Fungible Token Standard, and pre-dates them both.
Curio Cards are all sold out, but that doesn’t mean you still can’t collect them! Cards in the hands of individual owners often get relisted for sale or trade. Visit Curio Cards on OpenSea
