Abstract: An image display consisting of an image grid (11) having a plurality of successive strips (68A-D) of each image disposed in parallel relationship to each other, and a masking grid (9) having a plurality of parallel window strips (64A) through which some image strips (68A-D) are visible whilst others are obscured and different images can be observed by relative movement between the grids (9, 11), the grids (9, 11) including grid alignment means (60A, 66) for use in aligning the image strips (68AD) of the image grid (11) and the window strips (64A) of the masking grid (9) in substantially parallel relationship with each other, and further including grid registration means (60A, 61A-D, 62A-C) for bringing various of the images of the image grid (11) into registration with the window strips (64A) of the masking grid (9) when the grids (9, 11) are moved relative to each other after they have been brought into substantially parallel relationship with each other using the grid alignment means (60A, 66).

Abstract: A poster display system for displaying a plurality of different images which includes an image grid with interlaced strips from the various images, masking grid adjacent the image grid having spaced apart masking strips alternating with spaced apart window strips, a mounting system for mounting the image grid and the masking grid for movement relative to one another, a drive mechanism for producing relative movement between the image grid and the masking grip between successive display positions in which the window strips of the masking grid are aligned with image strips of a particular image, the image strips of the other images being obscured by the masking strips, and compression means for urging opposite edge portions of the image grid and of the masking grip towards each other whereby the image grid and the masking grid become curved and the image grid and the masking grid are brought into intimate contact with one another under pressure.
