Note to Eric - Sorry I have no provenance for this photo.
Looks very English ??
The chauffeur had to start the car, then maybe the group of ladies could take a test drive around the lawn?
(often there are more people in old automotive photos than could fit in the car or motorcycle + the one who took the picture)
They must be going on a trip...I see the chauffeur has all the the bags loaded in the car
The car has flowers all over it. It is either a holiday or she ran through a rose garden and he finally caught up with them to get the car stopped.
What year do you think the car is?
