Abstract
Abstract An informational apparatus which includes a plurality of pages of printed material and means for storing a recorded audio message integrally therewith. A preferred embodiment of the apparatus resembles the shape and construction of a book. The printed pages of a single signature are disposed on both sides of an audio recording storage case. The signature is secured to the case so as to form a complete unit. The case includes a frame defining an opening therethrough. Secured by suitable adhesive to the front and back surfaces of the frame and obstructing a portion of the opening defined by the frame is an inner cover. In this manner, a pocket is formed within the frame for receiving and securely retaining an audio recording.
