Art Brokerage: Diane Anderson American Artist: Diane Anderson, born in Chicago, has developed a national following as a landscape artist. After graduating from the University of Iowa, she devoted herself to a career in art, working long and hard to refine her considerable artistic talents. With her mastery of watercolors and eye for detail, Diane strives to create in her landscapes not so much a scene as a feeling; not so much a place as a memory. A sunlit clearing in the forest, a placid meadow pond, or a waterfall shrouded in early morning mist - these are the kinds of chance, momentary encounters Diane recreates. Listings wanted.
