A pair of women standing on the drive in the front garden of their house.
This picture is in the 'Singapore' series, because one of the women, the one on the right, has featured in some of the pictures which were at RAF Seletar. I suspect this picture is not in Singapore, but possibly a photo taken when the RAF serviceman was either on holiday back in the UK, or had returned to the UK after his posting. The location is unknown, but obviously, the house was number 11.
This was taken on 127 format colour slide film in (probably) the 1960s.
