Abstract: A toy telephone with a spring-powered phonograph in the telephone base that is operated by a drawstring. The drawstring is attached to the telephone handset, in the manner of a telephone cord, so that the phonograph is operated by pulling the handset away from the base and then releasing it. The drawstring is long enough to allow a child to hold the handset to his ear even when the drawstring is fully rewound into the telephone base.
