The Signature by Simon de la Rouviere (@simondlr). Mint here: https://etherscan.io/address/0xcd78b15a249edf0416F89e4BF131fe4416d94FF9#writeContract

A conceptual art project that emphasises the provenance of an NFT. All pieces look the same. Anyone can mint a "signature" at any time (only pay gas). No restrictions. Uncapped supply. The only way they differ is when it was minted & by whom. Over time, if transferred, a piece will attract more signatures from more holders.

It's all about the signature. Just follow it.
