Stormtrooper Viewfinder, POTF2, 1996-1997
This 3-3/4" Stormtrooper is a conceptual prototype that features a "Viewfinder" like feature in the head. It is a production figure that was modified with an eye port on the back of the head. The front left eye was hollowed out to allow for light. When you hold the figure to the light, you can see a still image of the trash compactor scene in Star Wars. Ultimately this design was never approved and this is the only example known to exist.
