Mrs. Carter took her fur coat to Reichlin Furriers to be cleaned and stored. She was given a receipt for the coat. On the front of the receipt an employee had written the number “100.” On the back of the receipt, the words, “the . . . amount recoverable for loss or damage to this article shall not exceed . . . the depositor’s valuation appearing in this receipt . . .” Also on the front of the receipt was a place for the customer’s signature, but Mrs. Carter had not signed it. The coat was lost. Is Reichlin liable for its market value of $450 or only for the $100? (Carter v. Reichlin Furriers, 386 A.2d 648)
