Abstract

312,961. Ward, C. W. March 1, 1928. Changing by alteration in view-point of observer.-An advertising sign &c. comprises a flat, convex, concave, or other shaped sheet 26 of fluted or corrugated glass &c. spaced in front of a picture &c. 14 at such a distance that it produces distortion of the picture without obstructing or breaking the continuity of any part thereof, and presents an appearance of movement when relative motion occurs between the observer and the sign. The flutings are shallow and may be in one direction only or be crossed. Two separate sheets having parallel flutings may be arranged so that their flutings cross. Fig. 5 shows in sectional plan a casing 30 having grooves 32 to receive the picture 14, a lamp being provided in a separate chamber at the bottom.
