Bantam Midget 19"
The 1930s saw the rise of hand built model racecars, known as spindizzies or tether cars.
Miniature racecars built by hobbyists zoomed around banked wooden tracks at speeds approaching 150 miles per hour.
Resembling the full-size racers of their day, several spindizzies competed at once, tethered by cables to a central pole.
Powered by model airplane engines, spindizzies raced against the clock.
