SPENCER DELINEASCOPE is made perfect because it is an IDEAL STEREOPTICON for both lantern slides and opaque objects, such as pictures, post-cards, reading matter and objects of all kinds dead and alive. IDEAL, because it embodies basic ideas (patented) possessed by no other. Example: Mechanical means of handling the slides, which does away with the antiquated lanternslide holder and at the same time gives a "dissolving effect" on the screen unattained with other outfits except by using two stereopticons, one above the other. One Spencer Delineascope does it. Spencer's Delineascope Model 3 for both lantern slides and opaque objects. 1,000 Watt Mazda bulb illuminant.
