visiting a library. In 2008, the Mercury crater Sander was named after him. Ownership rights In 1992, Gerd Sander, August's son, sold the archive to German nonprofit art foundation SK Stiftung Kultur. It is on display at Die Photographische Sammlung/SK Stiftung Kultur. In 2017 Julian Sander, Gerd's son, claimed to represent August's estate, and issued a press release stating that the archive would now be housed by Hauser & Wirth. The claim has been disputed by SK Stiftung Kultur, and the ownership dispute is still ongoing. In 2022, Julian Sander made available non-fungible tokens (NFTs) of the entire 10,700 archive of Sander negatives on NFT platform OpenSea. Buying a Sander NFT was free apart from initial upload fees. However for all resale transactions thereon, via a smart contract Julian Sander would receive 7.5% of the resale cost and photographer Alejandro Cartagena's Fellowship Trust would receive 2.5%. All NFTs in the collection were claimed and, within a few weeks, over 400 ETH was traded in secondary sales on OpenSea. Soon and without warning, the archive was delisted from OpenSea because SK Stiftung Kultur claimed that as it owns the copyright to Sander's work until 2034, the NFT collection is thus in violation of copyright law. Julian Sander argues that the doctrine of fair use allows him to publish the images in such commercial settings.
