Sandy Lepore, regarded by many as an expert on Vincent, has over her twenty six years as a dealer placed many pictures executed by Harry A. Vincent; and one can usually find examples in her present inventory. In addition to Harry A. Vincent, Lepore Fine Arts specializes in artists painting between 1850 and 1950 with a focus on artists who painted in New England during this period.
