I received a Marx figure 8 set for Christmas 1960. Cars were a red C1 Corvette and a blue '60 T-Bird. On Christmas Day my older brother and BIL ran them so hard the windshield melted out of the 'Bird.
I expanded on that with Aurora AFX track and various cars including the hop-up kits etc. Had a couple that would launch hard enough to pull the pin out of the groove LOL!
Since I grew up in a twelve room Victorian house I devoted one upstairs bedroom to slot cars, set up on an old dining room table with several leaves. Not sure that I have any pix.
