"Andrew Wyeth: The Helga Pictures," some 120 drawings and watercolors by the American realist painter, will be shown at the Detroit Institute of Arts Nov. 15, 1988-Jan. 22, 1989.

The museum says, "Wyeth is one of only a few American artists to capture the interest and admiration of the public on a broad scale. We now offer the most controversial body of work he has ever produced."The works, depicting a neighbor of Wyeth's, were executed between 1971 and 1985. "They represent an unusual look at the working methods of an artist as well as a cumulative account of Wyeth's personal style."
