double exposure by accident

there was this filmroll I was badly searching for after my half-a-year-stay in iceland. I couldn't explain myself what happened to the pictures on that film. I seemed to have lost that roll.

now I developed the pictures I took at iceland airwaves festival. kinda shocked finding out that I double/triple exposed the lost filmroll which now contains pictures taken in iceland in may, pictures taken in vienna in late summer and pictures taken in iceland again in oct.2012, all mixed up and layered.
definitely one of the more pleasant kind of accidents.
