a rear element which has a rear fine pattern of visually contrasting areas which is dissimilar from said front fine pattern and which cooperates with said front pattern to produce a field, said field presenting changing visual effects when the front pattern occupies different positions relative to a line of sight from a viewer'"'"'s eye to said rear pattern, said primary copy being repeated on said rear element effectively in register with said primary copy on the front element, and secondary copy on the rear element, all said copy on the rear element contrasting visually with said rear pattern and the margins of all the characters of said secondary copy being defined by the rear pattern and said secondary copy being visible through parts of said front pattern;

Abstract
A point of purchase advertising display device has a front element and a rear element which are spaced a short distance apart and back illuminated. Primary copy is transparent or translucent on the front element and is repeated on the rear element in translucent form in register with that on the front element. A front fine pattern of transparent and opaque areas occupies the rest of the front element and defines the margins of each character in the primary copy. Translucent secondary copy on the rear element is viewed through parts of the front pattern, and the rest of the rear element consists of a rear fine pattern of translucent and opaque areas which is dissimilar from the front pattern but cooperates with the front pattern to produce a field of changing visual effects as a person moves relative to the display device. The rear fine pattern defines the margins of each character in the copy on the rear element. The appearance of the secondary copy changes clearly but subtly as the visual effects of the field change.
