Vintage Japan brass mid century butterflies wall hangings mcm 2 sizes

Vintage Brass Butterfly Wall Art Décor STYLE HOUSE Japan Pair 16" & 13" Pair of lovely brass butterflies  - wall hanging loop hooks on back of each. Both are marked JAPAN (center back). The larger of the 2 measures 16" across and the smaller 13" across. There is some patina and I have not cleaned them. I cannot tell if wire antennae are brass but they are fully intact. Great style! Very good overall condition for age. SEE PHOTOS
