NFTs are unique digital tokens that are often attributed to art that has no physical representation.
Chloe Clem, now 10, became famous in 2013 when her mother shared her unimpressed reaction to a surprise Disneyland trip online.
The image has become a popular meme for expressing concern.
An NFT provides a digital certificate of ownership for the piece but bears no copyright. Therefore the winner of the auction will own the digital token representing the meme, but not the meme itself.
NFTs are usually bought in cryptocurrencies, so the transaction is recorded on a publicly available ledger called the blockchain.
Digital artworks have come under fire recently due to environmental concerns, as vast amounts of energy are required to mine cryptocurrencies, process transactions, and maintain the blockchain.
