A client of the firm, Will-Maker Edward May, executed a Will that your supervising lawyer prepared for him two years ago. May has been storing the original Will in his safety deposit box and your firm has a copy. Today May telephones you and instructs you to add a valuable new painting to the specific gifts his son will receive. He asks you to add the painting to the clause in the Will that provides specific gifts to his son and to send him a copy so that he can discard the old Will and put the revised one in his safety deposit box. Explain whether the change to the Will will be valid if you follow these instructions
