Abstract: An advertising kiosk for holding a pair of translucent sheets of advertising copy. The kiosk is particularly suited for outdoor use and has a totally enclosed housing with pair of windows in which the sheets of the advertising copy are located. Plural fluorescent lamps are mounted at equidistantly spaced locations adjacent the windows and behind each sheet of advertising copy on a movable frame. Each window of the kiosk is covered by a transparent outer panel having an inner surface behind which the advertising copy is mounted. The advertising copy is held in place by a flexible diffuser sheet hingedly connected to the housing. Each diffuser sheet is adapted to flex into engagement with the advertising copy, whereupon the advertising copy is held tightly and evenly against the inner surface of the outer panel. The lamps provide even light through the diffuser sheet, the advertising copy and the outer panel, to illuminate the advertising copy for visibility by persons outside of the kiosk.
