How much would you be willing to shell out for your favourite piece of horse racing art? Is £20 million out of your

range?

According to a report by The Guardian, 'Gimcrack on Newmarket Heath' by artist George Stubbs is expected to appear at auction this summer with an estimated pre-sale price of £20 million.

"It is unquestionably one of Stubbs' most important paintings and one of the greatest racing pictures ever painted," Christie's spokesman John Stainton was quoted as saying in the report.

The painting is a combination of two images: a horse racing and being rubbed down.

The painting was commissioned in 1765, and Stainton was cited as saying that it is one of the most valuable old master paintings to appear at auction.
