ABSTRACT:
An aural-visual display system especially suitable for visually displaying a number of items, such as products, and playing a recorded message relating to a displayed item in response to actuation of a selector corresponding to the item. One of a number of different messages on a magnetic tape are selectively played by changing the positional relationship between a magnetic pickup and the message location on the tape, in response to operation of a selector. This concurrently produces a visual display associated with the selected item to which the message relates.
