Probably seen before - but new to me:
"27th April 1931: English industrialist Sir Herbert Austin locks an Austin 7 at Pass & Joyce's showrooms before shuffling the key with the other keys in the pile on the floor. The person who picks out the right key wins the car."
The car is new - but notice the precautionary drip tray.
As a prominent London dealership, why did Pass & Joyce think it nessecary to describe Sir Herbert as an "Englsh industriallist"? As for the shovel for key mixing, I shall leave any further comment to the ooh matron brigade, who have already risen to the occasion.
