This is As If I Were from The Most Expensive Artworks Project collaboration by Athena Novo and Mad Monk.

It is a remix of Modigliani's Nu Couche Sur Le Cote Gauche within itself . It is No 17 (skipping a lot in between at will) in the project in parallel with its place on the list. Accordingly it has been last sold November 2018 in Sotheby's New York for USD 157 million. The sellers were Enza and David Nahmad and the buyer was not disclosed.

The Most Expensive Artworks Project started with an idea and a web page on Wikipedia: https://en.wikipedia.org/wiki/List_of_most_expensive_paintings.

Athena Novo and Mad Monk collaborated on "doing something" with the list. First idea was to make a common "burn" GIF. Step by step the original or an alternative version would be burned i.e. like a GIF. However the idea of destructing artworks did not appeal. Then glitching was cast off as the main tool for something more appealing was under consideration. It was the idea of remixing the artwork more freely - sometimes with itself and sometimes with others on the list (as a pre-condition to narrow the universe).

Consequently AN and MM started to work on from the top of the list. Several results were obtained and from them, the story modes with multiple artworks will be minted on Async Art by Athena Novo while the single items (in GIF or JPG) will be minted on various platforms as a part of the collaboration.

Nu couché (sur le côté gauche) is a 1917 painting by Amedeo Modigliani. The painting was included in a 2017/2018 Tate Modern exhibition of Modigliani's works. The painting was sold by auction by Sotheby's in April 2018. Writing in The Guardian, British arts journalist Jonathan Jones compared it to Ingres' 1814 work Grande Odalisque.
