My paternal grandparents loved to go on picnics ("coffee outings") in the summer. My grandmother Sally would pack a picnic basket with a coffee thermos, cups and saucers (porcelain, not plastic), and some buns and biscuits to eat. I'm not sure who the couple in the middle are, but it's Sally to the left, and her sister Hildur with husband Olle to the right; and I think it's probably from the mid/late 1950s.
