Titled just 'Ethereum', this design was printed off as a calling card for an ETHLDN meetup event at Imperial College London, at which Vitalik Buterin himself spoke! The event took place on 02/09/2019. This version has been specially made for the blockchain, and consists of just TEN individually serial numbered designs. This is serial number ETH-KO-02. The works are being uploaded via KnownOrigin as seperate NFTs - one for each serial number.
