Liddell Hart declared that Sherman was "the most original genius of the American Civil War". The cabinet card measures about 6 1/2" x 4 1/4".
Too large to be considered a CDV. NOT A MODERN COPY OR REPRODUCTION! This is a circa 1863 studio photograph..
Possibly made a year or two latter. Guaranteed to be original 19th century manufacture.
Do not pass it up! Historians and civil war aficionados will love it in their collection!
