Mystery wedding picture

This is a photo with a story. Years ago (>7), Marlies found this large print of a wedding photo hidden in the house that she moved into. A photographer herself, she decided to keep it and hang it. She doesn't know who the people in the picture are, but she got asked once whether she was a daugther of previous inhabitants of the house, presumably these people.

In the meantime she moved, and moved the picture with her. And here it is again, in the house where I am staying these days. I've always loved it, it seems to tell so much by itself! And I love it even more, now that Marten and I had our own wedding pictures taken at the exact same locations in the Noorderplantsoen (Groningen).
