Research: https://www.thecollector.com/top-10-african-oceanic-art-sold-in-the-last-decade/ In the 1960s, both Sotheby’s and Christie’s opened up new departments specializing in art from the previously overlooked continents of Africa and Oceania. Pieces of art from across Sub-Saharan Africa, Australia, Melanesia, Micronesia, Polynesia and Indonesia became more accessible than ever to collectors, many of whom proved willing to part with incredible sums of money in exchange for a tribal sculpture, ritual mask or ancestral figure. Some of the most exceptional purchases of Oceanic and African art have been in the past decade, with seven-figure auction results (and even one eight-figure!) appearing regularly.
This African mask was purchased in the USA. If you need more photos, will return to the storage and take them in accordance with your detailed request.
This is a carved wooden mask probably from West Africa. Pieces like this have been made in Angola in the early 20th century.
The hair appears to be made of straw. I was able to find similar pieces sold at auction. Pre-auctions estimates ranged quite a bit and generally were higher than hammer prices. Some estimates for masks were as high as $400. However, my estimate is in line with realized sales. The Fair Market Value of this mask, based on sales, is between $100 and $200.
