Either way it's worth quite a bit but I just heard someone scoff and say Cooper's is unsigned which even with the provenance:

'We found it rolled up in a tube': Alice Cooper discovers Warhol classic after 40 years
The rock star Alice Cooper has found an Andy Warhol masterpiece that could be worth millions “rolled up in a tube” in a storage locker, where it lay forgotten for more than 40 years.
The work in question is a red Little Electric Chair silkscreen, from Warhol’s Death and Disaster series. Never stretched on a frame, it sat in storage alongside touring artefacts including an electric chair that Cooper used in the early 70s as part of his ghoulish stage show.
According to Shep Gordon, the singer’s longtime manager, Cooper and Warhol became friends at the famous Max’s Kansas City venue in New York City.
“It was back in 72 and Alice had moved to New York with his girlfriend Cindy Lang,” Gordon told the Guardian. “Andy was kind of a groupie, and so was Alice. They loved famous people. So they started a relationship, and they loved to hang out.”
Warhol went to see a concert in which Cooper feigned electrocution in a chair identical to the one in Warhol’s print. The image is based on a press photographfrom 13 January 1953 of the death chamber at Sing Sing prison, where Julius and Ethel Rosenberg were executed that year for conspiring to pass atomic secrets to the Russians.
Lang, a model and Interview magazine cover star who died in January at the age of 67, had the idea to approach the artist’s studio and purchase one of the 1964 canvases.
“As I recall,” Gordon said, “Cindy came to me for $2,500 for the painting. At the time Alice is making two albums a year and touring the rest of the time. It was a rock’n’roll time, none of us thought about anything. He ends up going into an insane asylum for his drinking and then leaves New York for LA.
“Alice says he remembers having a conversation with Warhol about the picture. He thinks the conversation was real, but he couldn’t put his hand on a Bible and say that it was.”...MOREHT: ArtNews who also note: "People are now buying art with Bitcoin, as well as other digital tender, including Ethereum, Ethereum Classic, Dash, Litecoin.
