Lucite Acrylic Flowers Pink Purple Brooch Vintage

Beautiful vintage molded flower pin in translucent pink and purple plastic -- looks like acrylic to me, but could be lucite. Pretty colors and dimensional look, with little faux pearls dotting the centers. Great vintage condition overall, with the metal backing starting to detach from one flower, but it doesn't look like it's in any danger of falling off. C-catch backing, unmarked, and pin measures 1 3/4" x 1 1/8".
