The formal name of the peep show machine was the Mutoscope -- at least when it was manufactured by the American Mutoscope & Biograph Company, which later became simply "Biograph" and is best remembered for the films directed by D.W. Griffith with G.W. "Billy" Bitzer as him cameraman.At this point, however, Griffith was a struggling stage actor and Bitzer was a leading cameraman for Biograph. This meant that he did all sorts of movies, including peep shows, and this is one of them. The title tells all and the show shows a lot as a woman exposes a shapely limb and is punished for her flouting of decent behavior. It may look stupid today, but this sort of Mauve Decade smut was what paid the bills.
