I remember when these were in the stores..
I believe these came from 3 Acrylic box 3-car sets, and the rest were 100% singles?
I always thought it would be cool... yet pretty much cost prohibitive, if not impossible logistically...
..to be able to buy a Hot Wheels car at each of the Hard Rock Cafe's with the name of that location on it! (like the t-shirts)
What a collection that would make!
