We had driven down a track we hadn't been along before and found the village of Pitonga at the end, facing the Ndogo Lagoon. Friendly people entertained us with strange purple fruit, atanga https://en.wikipedia.org/wiki/Dacryodes_edulis), boiled in an aluminium kettle. I asked the Pitonga chief about these baskets that we'd seen in use and some days later, these two examples appeared. So, not old (this was mid 90s), not used, but a fine association with place, time and culture.

Delightfully, there's a similar though smaller example from the neighbouring Punu in the Musée Quai Branly (Paris), donated by André Raponda Walker to Musée de l'Homme (Afrique) in 1937 http://collections.quaibranly.fr/#dc6aa409-9c65-4163-be3d-66a0745944fd
