I feel this is quite a hard challenge – the only real clues are the writing on the board in the top right hand corner which looks Polish to me. The challenge here is to try to find the location but any other information would be great.
Your aim is to try to find information about the picture using only the visual clues in the picture. In order to help, the scan is a higher resolution than that normally used on Found-Film, and there is a magnifier set up to give you a more detailed look- just hold the mouse cursor over any part of the picture to try. The type of challenge is shown above the picture and you can answer with a google maps link in a comment.
There is no prize for this other than the joy of knowing you got it right and the fun of doing it, but if it proves popular I might publish an honour board every month
