Excelsior Sound Effects Cabinet

Here is an ad for a sound effects cabinet that appeared in the 25 January 1913 issue of Moving Picture World. From the image, you can see that the cabinet was operated through a series of knobs and levers, with the sound effect traps hidden within the cabinet itself. The ad also emphasizes the ease with which the cabinet could be operated—implying that it did not require an expert and so could be used to trim labor costs, a most important consideration especially for small exhibitors.
