Chokwe Pwo / Mwana Pwo Mask (Angola)

Based on your third image, you have a classic example of a Chokwe (or Tchokwe) mask from Angola, known as a Pwo or Mwana Pwo.

While the previous two objects you shared were stationary shrine altars, this is a masquerade mask designed to be worn in performance.

1. Identity and Gender

Pwo / Mwana Pwo: These terms refer to the "fulfilled woman" or "young woman." Although the mask represents a female ancestor and the pinnacle of feminine beauty, it is exclusively carved and danced by men.
Matrilineal Honor: The Chokwe are a matrilineal society. This mask is danced to honor women who have successfully survived childbirth and to bring fertility and prosperity to the community.

The carving follows the "canons" of Chokwe aesthetics:

Red Pigment (Tukula): The deep reddish-brown color is achieved by rubbing the wood with a mixture of red camwood powder (tukula) and oil. This signifies the red clay traditionally applied to women's skin during initiation rites to represent health and fertility.
Horizontal Slit Eyes: Notice the eyes are narrow slits set within large, concave sockets. This symbolizes the spirit's ability to see into the invisible world ("second sight").
The "Block" Mouth: The mouth is carved as a protruding, rectangular block, often slightly open. In some variants, this reveals filed teeth, which were a historical mark of beauty among the Chokwe.
Pocked Scarification (Masyoji): The dense dotted patterns on the cheeks are representations of tattoos or scarification. These specific markings are often called masyoji, which translates to "tears." They represent the mixed joy and sorrow a mother feels when her son grows up and leaves her to join the men's society.
