That auction is from the Budget Bicycle Center in downtown Madison Wisconsin.

It’s a huge new & used shop that’s located in four different buildings, one of which that could best be described as a small warehouse. And it’s packed wall to wall and hanging from the ceiling!
Really a pretty amazing place to just to walk through, I was there about a year ago and the highlight for me was that they had a authentic bone shaker on display.
Unfortunately their antique & vintage bike prices are definitely on the unreasonably high side.
