Correct!
This early slide projector was made around 1910 by the German
toymaking firm of Carette.
It uses a paraffin lamp as the light source, the chimney on top is to let
the heat out. The glass slides have pictures printed on them and are moved
sideways by hand. The distance to the screen (usually a wall) was normally
only a metre or two and the room had to be very dark in order to see the pictures.
Most children had few, if any, toys so something such as this would have been
a prized possession. Giving a simple slide show would have been a great event
involving most of the family as projecting pictures on to a wall was almost
magical. Remember there were no televisions or radios in those days and very
few houses even in cities had electricity with gas, paraffin lamps or candles
being the usual method of illumination depending on where you lived.
