Art historians have recovered a collection of lost Andy Warhol paintings, which were never turned into physical prints, from 30-year-old Amiga floppy disks.

In 1985, computer and electronics manufacturer Commodore International commissioned Andy Warhol to create art using the company’s Amiga 1000 computer. Warhol saved many of his experimental images to Amiga floppy disks.

The Andy Warhol Museum added those disks to its collection in 1994, but it wasn’t until last year that historians realized the disks held undiscovered works of art. But by that time, the file formats of the saved images had become obsolete. A team of archivists and computer researchers used custom software to recover the images.

The paintings include a trademark Warhol soup can and a modified Botticelli in which Venus sports an extra eye.

“Warhol saw no limits to his art practice," said Eric Shiner, the director of the Andy Warhol Museum. "These computer-generated images underscore his spirit of experimentation and his willingness to embrace new media — qualities which, in many ways, defined his practice from the early 1960s onwards."
