Abstract: An advertising device fabricated of a single piece of flexible material and cut to form an inverted T-shaped structure. The device comprises a top section and a base section, the two sections being separated in part by perforations, the base section being insertable into a rounded cup holder, such that the base section bends and engages at least a portion of the inside surface of the holder. The device is held in the holder by the forces of friction. The advertising and/or promotional materials are presented on the top and base sections which can be easily separated.
