Gibson Danes, head of the art department at Yale University, awakened Mrs. Grunewald's interest in art when she was a student and he a professor at Stephens College, Columbia, Mo. After her marriage to Mr. Grunewald, her husband became interested in art, too, and now this small den holds scores of books on the subject. Art in the room includes (from left) a painting by the late Hutton Webster of an old mission, "Moths," by Mac Schweitzer, a Cezanne (in window) and a wood carving of a small child at the beach. On the fireplace mantel (not shown) are a 16th and a 17th century icon and a picture done by the Italian artist Fappiani in colored beeswax.
