For the race car fans out there.  This 1953 photo shows Stuart Lewis-Evans and Tony Harris lowering their Cooper Mk VIIa 500cc Formula 3 from the carrier atop a Series I.  The track was Crystal Palace in London.

Tragically, Lewis-Evans died in 1958 at the Moroccan Grand Prix when his engine seized, sending him into the wall at high speed, where his car burst into flames.
