Have to see if I can find it on demand.
I was a target demographic for these. My Grandfather traveled for his job during this same time frame and he would always pick one up for me. had one of the original wheel shaped cases and eventually had to graduate into a large suitcase style carrier. I've still got a handful of the originals around somewhere. Doubt they are worth much as they have racked up some miles. I still pick up 1/64 cars on occasion, but now they go into a box still on their bubble card.
The big question- how many of you got a smacking with a hot wheels track?
Not from my parents, but my Bro and I went after each other numerous times.
