The self-portrait, valued at $10-15m (£6.5-9.7m) and about 2.7 sq metres, was produced in 1986 and at the time Warhol's dealer, Anthony D'Offay, was quite taken aback by it. "When D'Offay saw the paintings he said they were too scary, too prophetic. He was worried about Warhol not being well," said Meyer. As it turned out, Warhol died unexpectedly the following year.
"Don't see it as a self-portrait, see it as a disaster painting. This is a ghost."
There are five in the series. The yellow, blue and green ones are in museums and the privately-owned red one is unlikely to come to market any time soon. I'll start the bidding at one copy of the Green Party's manifesto.
