Washington, an insane person of limited means, entered into a contract with Lincoln for the purchase of an antique axe and a cherry tree for $100. The price paid for both of these items was fair and reasonable and, at the time the agreement was made, Washington seemed to be a normal person. Subsequently, Washington refused to take delivery of either the axe or the cherry tree, or to pay for them.

Was there a valid contract between Washington and Lincoln for the purchase and sale of the antique axe and cherry tree for $100?
