Focus on The Harvest Wagon and discuss the Provenance.
The first work could not find a buyer, perhaps being too ribald for the art market of the time.  It was given to Gainsborough's friend Wiltshire, a mover who transported Gainsborough's paintings from Bath to exhibitions in London. Wiltshire's horses had also served as the model of the animals in the picture. The painting remained in Wiltshire's family until his grandson sold it in 1867.
The second painting, done at the height of Gainsborough's fame, was sold to the Prince of Wales, later to become King George IV. It later became part of the collection of American steel magnate Elbert Henry Gary. Upon Gary's death in 1927 his collection was auctioned off, and The Harvest Wagon was one of the most sought-after works. After a competitive auction it was purchased by art dealer Joseph Duveen for $360,000, then the highest price ever paid at auction for a painting in the United States. Duveen later sold it to Canadian art collector Frank P. Wood for $450,000, and Wood then donated it to the Art Gallery of Ontario. In 1959 the painting was somewhat damaged during an attempted robbery when the thieves tried to cut the painting out of its frame.
