This is interesting simply because it is the first APS film I've posted onto Found Film but there is something slightly more interesting as well. The slide is in a Boots plastic mount so was probably a film bought and processed at Boots in the UK. The actual slide mount is a 35mm mount however and it's possible to see the edge of the film which states it is Kodak film. I wonder if Boots film was actually re-packaged Kodak film (seems likely) or if this is just re-use of a slide mount by the photographer?
Because the film is APS, I've dated the image as 1990 - 2000.
