While the Menorah shaped pipe stand is interesting, collection presents something of a pile of crap. It's possible that Einstein bought crap pipes, though images of him smoking a pipe show fairly standard pipes.
The "provenance" is really non existent. The seller's father brought home this crap collection between 25 and 35 years after Einstein's death and didn't start work at Princeton until 14 years after Einstein fell off the perch.
Since the story goes that the houses where faculty lived were cleared out after the occupant departed, why would these pipes still be hanging around 25 to 35 years later?
There is nothing in the "provenance" that directly ties this crap set of pipes to Einstein, and it doesn't take an Einstein to figure that out.
All I can add is that the gullible nitwits bidding on this assortment of crap are certainly no Einsteins.
