ABSTRACT:
An advertising device includes a plurality of information-bearing sheets mounted on the periphery of a rotating drum for pivoting about axes which extend parallel to the axis of rotation of the drum. A displaying arrangement holds the successive sheets in substantially vertical positions for a predetermined period of time so as to display the information on such sheets. The drive arrangement for the drum also drives the capstan of a tape recorder so that sound effects are produced which pertain to the then displayed information. The rotation of the capstan is proportionate to the rotation of the drum so that the sounds are synchronized with the visual information.
