An indicia carrier film suitable for producing consecutively changing images in harmonious fashion. The indicia carrier includes a display unit housing provided with at least one panel formed from an array of linear lenses, a displaceable indicia carrier film which is disposed within the housing at a distance from the rear face of the lenticular panel equaling the focal length of the lenses, and a drive means for periodically displacing the indicia carrier relative to the lenses. The ratio of film weight to surface area is greater than 1:100 gm/cm2. The total weight of the film is not greater than 10 gm for an indicia carrier of approximate A4 dimensions (17 x 29.5 cm). The modulus of elasticity is of at least 600 Mpa.
