i bought a pair of these nakashima like art pieces on ebay for less then $20 for the pair. This is the nicer of the two, the other one is sun faded.
These had a nice story, came from a home of a famous executive, lots of mid century modern furniture pieces from eames, springer etc so these very well could be nakashima but i’m not aware of him making small pieces like this. And nakashima-like pieces are pretty easy to forge since he used natural organic forms it was hard for him to maintain a theme that you can identify.
They’re still nice art pieces for less then $20, better then generic stuff you buy at pottery barn.
