some background info..Christmas 1966 pic is my older brother Chris' first high rise bike, a Huffy Thunderbird there was another bike under the tree that year a Mattel vroom motor bike but the pic is lost.
Pictured in '67 pics is Chris sitting on a just out Huffy The Wheel with drag brake and red line tires and my pops sitting on my first two wheeler complete with training wheels and tassels as I recall the training wheels did not stay on to long.
