"Chrome Reverse and Baby Moons" were pretty popular in Southern Saskatchewan (where I grew up) In the early-to-mid 70's, and were in many of the speed shop flyers.
I think they were pretty popular because (as someone else said) they were an inexpesive alternative to Mags, like the Cragar SS's and the Keystone Klassic spokes (loved the look of those)
But yes ... I recall seeing lots of cars, like the GTX and Sport Fury's wearing Chrome reverse. I think they looked best on the bigger cars ... not so much on the "pony" cars.
