What to do with family photos? How many do your guests need/want to see? Do they really want to experience our memories all over again? I've never been huge on putting out lots of personal photos in common areas because of these dilemmas.
However, when I came across the following photo, it really struck home. It's like a little gallery in one concise location...a true trip down memory lane. We will have an upstairs gallery (open to the great room below) and a perfect wall for something along these lines.
This next image is another option although it shows artwork as compared to photographs. I suspect that it could be easily updated. In general, this is another inspiration photo for overall tones and colors as well.
