A portrait of a couple

A portrait of a couple taken on 127 medium format colour slide film. This is in the same series as the other family pictures taken on this film, and you can see those pictures using the 'Series' tab to the right. On the slide mount is written 'Mother & Dad' and then To wc. This could possibly be their surname - Towe or possibly a code the slide owner understood. The date must be around the same time as the other pictures in the series - about 1963.
