"In the 18th and 19th centuries a device with a lens and mirror called the zograscope was used to give an illusion of depth to hand colored engravings called vue d’optique prints.The 18th century zograscope prints seen here by GB Probst were spliced together from screenshots from the Gallica site at the BNF. The images posted below are cropped: in the border surrounds of the full prints, the title(s) are given (usually) in two to four languages and a mirror image of the basic title - specifically for the zograscope - usually appears at the top, above the illustration.
The zograscope is placed over a hand colored print so that the print is reflected in the mirror held at an angle. The spectator looks into the magnifying lens on the front of the instrument to view the reflection. The lens and mirror impart a quality of depth to the flat print. These instruments were popular parlor amusements in the 18th and early 19th centuries. It is a sort of peepshow without the box." [source]

A collection of some eighty hand-coloured engraved prints by Georg Balthasar Probst are available from the Gallica website. {once you load an image, click on 'Display' to get a full-screen, zooming interface} (And, as noted above**, clicking through on one particular image reveals a further eighty prints)
This Grand Perspectives post very much derives from an entry seen on the (excellent) Gallica blog a few months ago (in which you'll find a link to the whole collection of vue d'optique prints).
"Georg Balthasar Probst was a German artist, engraver and publisher in Augsburg, a major European publishing center in the 17th and 18th centuries. He produced architectural views of places around the world intended as vues d’optiques, which were published in various places during the last half of the 18th century, including Paris, Augsburg and London."
