Here's a bit of celluloid confection for your vintage hat or scarf...this Art Deco era jabot or hat pin. It's made with a slice of butterscotch celluloid that's topped with an arch of end-of-day mixed colors. The swirl of colors repeats on the bottom screw-on guard.
The pin measures 3 3/8 inches long by 1 3/8 inches wide. Circa 1930. Excellent condition.
