Westfront 1940, Photo with Descripton sheet

Description sheet is 21 x 15 cm large, it have sorting codes on the top and bottom for a sorting register. On the description sheet there is a photo in the size of 12 x 9 cm showing a destructed house in Belgium. The soldier making the photo is mentioned to the lover left.

Not really shure what it is for, interesting though.
