A digital collage just sold for more than $69 million at an online auction, according to news reports.

The artwork was produced by digital artist Mike Winkelmann, also known as Beeple, and is a composite of 5,000 individual drawings, according to the auction house Christie’s. Winkelmann began creating the work in May 2007, when he launched a project called “Everydays,” in which he committed to producing and posting a new piece of art online every day.
