Vintage 1920's Oil Painting African American Artist Signed A Rasamoelina

This is an original painting on either linen or maybe silk? It is by A Rasamoelina and was made in 1921.

It measures about 10" by 12". Most of her works we're of women from Madagascar. It is a true vintage item so has some signs of wear see photos. But such a great painting really captures such a strong woman!
