I have an envelope addressed to my grandfather from his wife's family in Czechoslovakia that was sent in the 1950s. The postmark is hard to read but I think it was sent in 1958. My grandfather died in 1948, but the family in Europe may not have known about his death. The envelope is full of photographs, some dated, some labeled, some with no information at all. The most poignant, which I will not publish for privacy reasons, is at the burial of one of my grandmother's great-nieces. There are photos of soldiers, of family groups, of children. The dates on the photographs range from 1948 to 1954.
These are my favorites.
