Chicago city directories for 1882, 1885, 1889 and 1991 show B. A. Mink as a photographer. A news item in the Chicago Interocean newspaper, 24 Jan 1885, shows John R. Scholl filed a bill in the circuit court against Benjamin A. Mink to dissolve co-partnership. From that evidence, the cabinet card here could have been finished between 1882 and 1885.
There is a seemingly endless array of legal notices about Mink and relatives, in law suits in Illinois, Wisconsin and Minnesota. He looks much like a bit of a flimflam artist.
