70s vintage African ebony wood carvings, turtle, man & woman carved figures

Early 70s vintage ebony wood carvings from Tanzania, all handmade. One is a turtle, there's also a man and a woman (the woman has a crack on one arm.

These were brought back to the US by a traveler nearly 50 years ago, and have been in that estate the entire time. I know very little about tribal art or souvenir pieces, but this lot was marked by the original owner (as show) for whatever that's worth.
