On May 17, 1988, Carlton was playing in the East End Open Golf Tournament. When he arrived at the ninth tee, he found a new Chevrolet Beretta, together with signs which proclaimed: HOLE-IN-ONE wins this 1988 Chevrolet Beretta GT Courtesy of Kerry-Lane Chevy $49.00 OVER FACTORY INVOICE in Paloma. Carlton aced the ninth hole and attempted to claim his prize. Kerry-Lane refused to deliver the car, however. Kerry-Lane had offered the car as a prize for a charity golf tournament sponsored by the Hershey-Paloma Sertoma Club two days earlier and had neglected to remove the car and signs prior to Carlton's hole-in-one. Carlton sued to compel delivery of the car. Would the doctrine of mistake provide a ground for Kerry-Lane to avoid the contract?
