I sure that this is actually just someone's dining room, but, for some reason, every time i see it, I think of some kind of hush hush backroom meeting of businessmen or something of the like. The stuffed bunny on the table kind of ruins that image, though. I would assume that the children have gone to bed and one of them left his or her toy behind.
If the two women and one of the men here didn't look so happy, I would assume that this might have been taken after a funeral given that they're all wearing black, but perhaps it was just a fashion statement. It certainly gives a nice effect in the picture coupled with the cheery, floral wallpaper.
Based on the other pictures in the lot that i bought this in, I believe that this snapshot was taken somewhere in Germany or Austria during the 1920's or so, maybe as early as the 1910's. Unfortunately, there is nothing written on the reverse to clarify.
