Inkie is also attending the Paris auction, where he was given a blank canvas and space on the sidewalk in a ritzy Parisian version of the mud-splattered Glastonbury day when he and Banksy painted the trailer. "We painted it live over a day," Inkie said after carefully peeling off a latex glove and offering a handshake. "He came up with the idea."
The trailer made its way to other festivals over the years, with Nathan driving and setting up tents as he had in the years before the spray paint hit his home. And it started to get more attention.
"Silent Majority" was painted freehand, rather than using stencils as has been Banksy's signature, and is a rare example of the artist's early work, said Mary McCarthy, a British street art expert who helped organize Monday's auction.
"This piece was a commissioned piece. So it wasn't a piece that Banksy just threw on the side of a truck or threw on a wall," McCarthy said. Nathan doesn't quite describe himself as a commissioner of artwork, but the piece became part of his life over more than a decade, after he met his wife and the two of them started a family.
"If I didn't like it, I would have painted over it," he said. "Then when he finished it, it looked great. You walk out your truck in the morning, open the door and there's 50 people taking photos."

Nathan said he hopes to build a house with the money from the proceeds, putting it on the same piece of land where the trailer stood for so long.
"We'll end up living in it again," he said. "It needs a different type of owner."
Banksy himself won't be at the auction, but the organization that he set up to authenticate his work has given "Silent Majority" a rare certificate that allows its buyer the unusual chance to own the piece legally. On his website, Banksy discussed the sale of street art.
"As a kid I always dreamt of growing up to be a character in Robin Hood," he wrote. "I just never realized I'd end up playing one of the gold coins."
