I spent the weekend sorting the photo negatives that had accumulated since 1996 as a relic from my analogue film era. While doing so, I noticed that negative strips are taped together in the laboratory, presumably so they can be pulled through the machine as one long film. After developing, the negatives are then divided into short sections and put into sleeves. The end of the film, however, is not cut at the sticky tape, but just before it. So you always find a few millimetres of the neighbouring film strip in your negative sleeve.
In itself, this isn’t an issue, if it weren’t for some cameras that squeeze a 37th picture onto a 36-exposure film. Usually, this goes well, and you actually find 37 prints in the photo wallet. Sometimes, however, the film is abruptly taped to the next film right at picture 37, and just like that, a few millimetres of that picture end up in a stranger’s negative sleeve.
These are the pictures I found in this way:

A large part of the picture is hidden by the sticky tape. If you could remove the adhesive without leaving any residue, you could see significantly more.
