Luvverly shot of a Bristol 403, the typically helpful Getty Images caption dates the shot as between 1940 and 1950 and notes the Eiffel Tower and Arc de Triomphe in Paris…
‘From Marble Arch to the French landmark by air ferry’ is a caption clue, so perhaps it’s a promotional shoot for a new service of moving cars around?
I think so, after a ferret around, note the shot below, i am not suggesting the car in the transport is a Bristol, wotizzit I wonder?
The aircraft is a Bristol Type 70 Mk32, a former military transport plane before its inaugural flight as a car ferry with Silver City Airways in 1949. These flights were between Lympne Airport in Kent and Le Touquet, France.

This photo was taken in March 1954, when this car, RHU999, was driven swiftly to Paris from Bristol UK, taking 5 hours and 5 minutes, including the Silver City flight from Lympne to Le Touquet.
