An old shed isn't exactly where you'd expect an artwork  by a famous painter to turn up, but that's exactly where a lost piece by British artist Alfred Munnings being auctioned off by Bonhams next month was discovered. The untitled, undated watercolor painting depicts a bucolic scene, with a pair of cows grazing in front of hay wagons.

The painting is expected to be among the highlights at the auction house's East Anglian Picture Sale in Knightsbridge, London on Tuesday, November 18, carrying an estimate of £8,000–12,000 ($13,000–19,000).
