Banksy, an anonymous graffiti artist who graduated from the U.K. streets to the auction rooms, will be represented in the London October sales with at least eight works at Sotheby’s.

Banksy’s “David,” a 2006 fiberglass tribute to Michelangelo’s 500-year-old statue in Florence, has a top estimate of 150,000 pounds ($299,655) for Sotheby’s contemporary art auction on Oct. 12, according to preliminary catalog information.

“Gangster Rat” from 2004, an acrylic and spray paint stencil on canvas, has a top estimate of 12,000 pounds for an Oct. 15-day sale.

Banksy spray-paints works of political satire in the London streets and has attracted collectors including artist Damien Hirst. Banksy’s record of 288,000 pounds was set for a design commissioned by the pop band Blur, at a Bonhams London auction in April, more than doubling the artist’s previous peak price.
