I underdstand what you have posted, but when you go to the Mecum "On Time" and bring up Atzbach Collection, it is not there.
The page you have posted I have brought up many times, but in order to bid, you have to register under that particular listing BUT, it is not on the "Mecum On Time" Atzbach Collection. Bring it up, and you'll see what I'm talking about.
I think you are confusing the Road Art auctions with the Mecum OnTime auctions. Q72 & Q170 are part of the Road Art auction ONLY.
There are several OnTime auctions that run for several days.
