I found this photo in a North Little Rock, Arkansas flea market. The label says "Mabel Vise Walker wife of Robert Walker". The photographer is "F.D. McGregor Osceola, Ark"
After research I believe the person is:
Mabel Ann Vise Walker
born 1896 in Illinois
daughter of Thomas J. Vise
mother of Carl Otho, Chester, Robert, Thomas, Charles, Edward, Dale, Joe L., Ralph
married Robert O. Walker (1894-?) on 22 Aug 1915 in Mississippi County, Arkansas
