This black plastic Stereocolor viewer was made in
Italy by The International Stereocolor Company, Bologna, Italy. It looks a little similar in style to the French
viewer, especially the slide advance mechanism, although it is a little
larger. The two halves of the
body are held together with small brass bolts and the slide advance
mechanism is all metal.
The slogan on the box translates to "The World in your
pocket in 3D Colour".
