- Description
- Instruments of this sort, which projected the image of objects placed on them, came into use in the second half of the nineteenth century. The “J. Duboscq / à Paris / No. 54” inscription on this example refers to Jules Duboscq, an important scientific instrument maker in Paris.
- This form came to be known, in the twentieth century, as a viewgraph or an overhead projector.
