Vintage Yale Wooden Paper Folding Fan

Vintage wooden fan made of paper with a Yale pennant on it. Very delicate and in very good condition with some surface soiling from use. When fanned out it measures 11 inches across and 10 3/4 inches top to bottom. When unfurled, a Yale flag in the school's color of blue displays beautifully. Difficult to date precisely, but these were popular at the turn of the 20th century.
