I have featured "postmortem photographs" several times (here, here, here, and here). The one above from 1910 is a bit different in that it features the deceased posed with classmates rather than family.
“Today, children are protected from viewing or actively participating in funerals with the deceased in plain view. In the first decades of the twentieth century, a popular style of postmortem photograph depicted dead school age children with their classmates or social peer groups, such as Boy Scouts. This photograph was made in the real photograph postcard format so that participants could have a copy and perhaps send one to friends.”Found at (OvO).
