During World War 2 Car was at the maternity unit in Shardeloes House, near Amersham. She was great friend of Mrs Tyrwhitt-Drake, who lived there.
Car made a painting of the activity, which is on the back of two of her windmill paintings. Although Car often painted on the back of other paintings, this the only known instance of her using two pieces of paper joined up.
A photograph in the collection held by the Amersham Museum records the same scene and confirms the location.
