I found an exact match of this one selling on 1st Dibs for $1200 describing it as Eames-inspired mid-century--the former seeming crazy but the latter seeming right. I have not being able to figure out who made it, but would guess there were not too many of them made; it feels very small batch to me. In any event, a lovely thing I think, made especially good by the round cutout on each side of the box, though one I have been wary to take all the way apart in fear of not being able to put it back together, in a timely way at least.
Box measures just shy of 3 inches cubed. Very good condition.
