This is a seven cassette recording of J.K. Rowling's Harry Potter and the Prisoner of Azkaban performed by Jim Dale. Unfortunately, I do not have a tape player to listen to the tapes and verify if they work or not. This is ultimately a gamble the buyer will have to take. But all seven are there and appear to be in amazing shape. The box itself has a little bit of mileage at the corners, but is in great shape. An amazing piece for anyone looking to add to their collection for cheap!
