Vintage African Bib retailer Necklace from 1960's, Glass, Bone, Brass Beads, Ethnical, Tribal

Striking vintage bib necklace from Africa.
Combination of black glass beads, white beads made of bones, gold color metal (brass?) beads.
It will look stunning on white, black, or gold dress. Very chic.

Original retailer owner purchased it in Africa in 1960's.
The second owner found it in local newspaper under "buy & sell" in mid 80's. When she saw the photo on the newspaper, she thought she had never seen such jewelry and "must have it". She drove over 3 hours in total to buy this necklace.

Some of the bone beads are chipped or have holes. Besides that, excellent vintage condition.
