The Persistence of Bovril Nightmares

Rarely a problem with modern digital cameras, this is an example of in-camera double exposure. There could be a couple of causes, but it was often annoying.

If it was accidental, it's definitely an "Oopsie".

If it was deliberate, it's Art. And it probably had a wanky title like "The Persistence of Bovril Nightmares".
