A Family portrait from the 1960s

This picture was taken on 127 format colour slide film, and although there is no date written on the slide mount, I would estimate that it was probably taken sometime in the 1960s. It was obviously taken with a flash, and in the evening because the daylight outside is gone.

Interesting that the boy in the picture is holding a clock – I wonder if this is a Christmas picture and the clock as a present?
