A stereoscopic picture viewing system having pairs of precisely aligned stereoscopic images arranged in rows on image carriers, with at least two pairs of images on each row, and with one image of each pair located between the two images of a different pair. In one embodiment, the image carriers are circular disks, with the image rows extending radially, and preferably having supplementary key indications at the inner radial ends of each row and in the spaces between the outer ends of successive rows. In another embodiment, the image carriers are long strips of wide film, either still film strips or motion picture film, with the image rows extending transversely across the width of the film strip. A cabinet is provided, for holding two identical image carriers in side-by-side relation, with two binocular viewers on the front wall of the cabinet, so that two persons in side-by-side relation may look through the two viewers and see simultaneously the same stereoscopic views as the two carriers are simultaneously moved to bring successive rows of images to viewing position. Either the binocular viewers or the image carriers are shiftable laterally to determine which of the pairs of images in each row will be aligned with and seen through the binocular viewers. In a variation, the cabinet is larger, accommodating a larger number of people for simultaneous viewing, and with provision for adjustment of the height of the viewers to different eye levels and provision for playing sound reproductions into loud speakers close to the ears of each viewing person. Other variations are disclosed, including a small hand-held viewer, and projectors for projecting images from the image carriers through polarizers onto a viewing screen, where the projected images are observed through polarizing spectacles.
