Vintage Black Glass Head Mannequin Made in Spain

The black glass head mannequin is in nice 1960's-1970's vintage condition. I didn't find any chips or cracks. It is glossy black glass and has a seam running down the middle. There is a pinhead size dot of silver on the back of the head which appears to be something that happened during the making of it. The top and back of the head have a slightly pebbled look but the face is smooth.

The head mannequin measures 11 1/2 in. High and about 6 in. Wide across top of the head. The base has a 4 1/4 in.
