James Ball Exhibit at Museum Center

This sounds like a good exhibit:

The Life and Photography of James Presley Ball
J.P. Ball was a 19th century African American daguerreotypist, entrepreneur, and abolitionist who lived and practiced in Cincinnati from 1849 to 1871. This exhibit chronicles Ball’s life and work through selections from Museum Center’s collection of more than 400 images, as well as artifacts and related archival materials. See the exhibit in the John A. Ruthven Exhibit Gallery. It is free and open to the public.
