This advertising panel comprises several bars H of triangular cross-section, juxtaposed in parallel in a frame A, and rotated simultaneously on themselves by means of spirals C fixed to a drive shaft N controlled by a step-down motor M, making it possible to produce three plane surfaces successively, each bearing a poster broken up into as many strips as there are bars H contained in the panel. This panel is characterised in that it includes a means of adjusting the bars H, allowing them to be brought together until their adjacent edges are contiguous, or to be spaced apart in order to leave a slight play which is necessary for the rotation. This adjustment means consists of movable supports D retaining the extremities of the axles K of the said bars, and stacked up on rods L with the interposition of elastic spacers E. <IMAGE>
