Bridget Riley's The Ivy Painting has sold for £413,000 ($614,296) at Sotheby's London, an increase of 129.4% on its £180,000 ($267,732) estimate.
The work was commissioned for renowned London restaurant The Ivy in 1998 where it hung on the ground floor, above table 32, and was composed to match the establishment's iconic stained glass windows.
 The piece belongs to Riley's 'Zig' series of paintings |
Sotheby's explained before the sale: "The Ivy painting demonstrates Riley's success in relating similar and contrasting colours in a way that sustains a saturated intensity of colour across the entire picture plane.
"It is executed on a smaller scale than most in the 'zig' paintings. In fact, Riley may have purposefully made it this size with its position in the restaurant in mind."
The lot was one of a selection of pieces consigned by the Ivy's management to raise funds for charity. The restaurant is undergoing an extensive refurbishment this year.
Sir Terry Frost's Sonnet to Black was another highlight, achieving £173,000 ($257,320) against a £100,000 ($148,740) estimate - up 73%.
The work was inspired by Another Sonnet to Black Itself, written in the 17th century by Lord Edward Herbert of Cherbury.
