This post card was taken by a photographer who lived next door to my grandparents' house in Hemel Hempstead about 90 years ago. It shows people at an exhibition - but can you help me to identify the venue, the date, and what connection there is (apart from the photographer) with Hemel Hempstead.
There are clues - the striking architecture of the doorway on the right should be sufficient to identify the venue, and text readable on the stall at maximum resolution suggest a Christian Missionary connection. The mock hospital entrance which appears to be the subject of the photograph is labelled "Ping Yin Hospital" so was a group (perhaps associated with Hemel Hempstead) raising funds for a new hospital in China?
