There will be no review of photographer Charles Eisenmann as it has already been done many times on the net. This page will just be for a small collection of cabinet cards that still show his studio imprint. These cabinet cards were printed for promotional purposes and as such, many copies can be found in various collections.
There are many accountings of the works of Charles Eisenmann available. Here are a few:

Surviving examples of the work of Charles Eisenmann show that he specialized in promotional photographs of circus performers and other actors. The Sutherland sisters were associated with Barnum and Bailey circus for about ten years.
There is a brief accounting of the Seven Sutherland Sisters HERE.
Some Eisenmann examples on this page have been enhanced for their presentation here. Many existing copies are in very poor condition. Most examples here are from auction sites.
Apparently many of the poses were re-printed several times on different occasions. Here is one of the same photographs mounted on the cabinet card with the studio imprint on the right.
This group portrait was probably done originally by Charles Eisenmann as it appears to be part of the series on Sutherland Sisters. The negatives appear to have been passed around to other photographers for re-printing as needed.
This one shows no studio or photographer identification.
