Diane owned a farm that she wanted to sell and ran an ad in the local newspaper. After George agreed to purchase the farm, Diane wrote him a letter saying that she would not sell it. He sued her to enforce the contract, and she raised the defense of the statute of frauds. The letter she had signed did not contain any of the terms of the sale. George, however, claimed that the newspaper ad could be combined with her letter to satisfy the statute of frauds. Was he correct?
