Unusual 1880s Cabinet Card Photo of Female Illusionist?

Interesting cabinet card that shows a woman that is obviously a performer of some kind.

The upper half of her body appears to be suspended on a trapeze with the bottom half of her body missing. The lady is identified on the back of the photo as, “Leah Hallet.” This name is printed on the mount, above the photographer’s name, Cassilly of St. Louis.
