Randolf, a wealthy connoisseur of arts, was invited to an art exhibition. He became

very interested in one of the showcased art exhibits and approached the manager to

buy the piece. While he was interested in the painting of the catalogue number

$1201,$ the art gallery's manager mistakenly assumed he was interested in another

piece. When it was time to complete the transaction, the manager realized that he

had instead sold and delivered the wrong painting and immediately clarified this with

Randolf. In this instance, the contract can be canceled by either party for:

homicide.

puffing.

negligence.

mutual mistake.
