KEYSTONE MOVIEGRAPH Projector, USA, c1919
   TICKETs for the MOVIEGRAPH HOME THEATRE
A very simple projector: An hand crank to turn the film on and a light source. Short 35mm. films were sold for that projector. The Keystone also produced similar projectors for 28mm and 16mm films.
The projector is very basically build - Is it a toy?? It can show magic lantern's slides too!
