Newscopy: "IT DOES, TOO--Mink, that is... grow on trees, we mean. In any event, something over 500 skins of natural Canadian wild mink are hanging on a 14-foot Christmas Tree on the first floor of I. Magnin's. Admiring it, as what woman wouldn't, are Jane Winter and Evelyn Hakala. Myriads of tiny brilliants in all colors illuminate the lustrous fur and there's a spherical golden sunburst at top. Decorations are worth more than $50,000."
