Notice the fine print, it is a collaboration between Bob Petersen (owned dozens of young adult magazines from the 50's to 70's including Hot Rod Magazine) and George Barris who had been a photographer and article writer for Hot Rod in the 1950s as he was getting his customizing business going
cantilevered roof, roof windows, spoiler...the Super Teen Machine! Windows swing up, cantilevered roof, V-8 engine, Hurst mag wheels, custom TV/Stereo console, custom hood, wide tread tires, custom buckets, overhead cam six engine, custom grille & bumperettes.
There were three of these cars made by George Barris. One for best group, one for best female, and one for best male singer. They were awarded on a Singer TV special called The Sounds Of '68 hosted by Ed Ames and Aretha Franklin.
The car that was won in the group category was won by The Things To Come from Albert Lea , Minnesota. It was a convertible--not the gull wing depicted in the model.
