This is apparently in the Joslyn’s collection in Omaha, Nebraska. I’m not sure if it’s being displayed right now, but they actually seem to have a pretty diverse collection ranging a large time period.
I had no idea Omaha had such a nice fine arts museum, might have to take a trip down there.
The comments on HN seem a bit envious of the original author with how they’re trying so hard to invalidate them.
Just how it came across to me.
