"Bidasoa" Spanish Porcelain Figurine /Satin Black Finish /Circa 1950's 60's

This was today's find at the Salvation Army Store. It's in mint condition and being black you would see even a minor defect. I have never heard of this company (Bidasoa) and there isn't much online either. The 13" figure itself is porcelain and is of a girl carrying water or wine vessels with one perched on top of her head. Her face is half covered by a veil. Quite pretty and a bit of a mystery. -Mike-
