I was at a funeral today and looking at the photo board that they always have now. I think this is something that is a fairly recent feature. I don't remember it at Grandma and Grandpa's funerals in the '70s. It's like salad bars. Someone thought of the obvious and next thing you knew everyone had one.
Looking at photos is an interesting experience. Even if you don't know the person whose photos they are. Of course in this case I knew her, but they would've been just as interesting otherwise.
What's interesting? You can peg the general era the photos were taken about every time. The formal class photo, an 8 x 10, soft color, the color nearly fake. Lots of greens and blues. Snapshots from the '30s and '40s. Still crisp, clear. 110 camera film from the '70s, the colors losing some of their realism, just about every time.
I also like the various poses. The fun poses that are almost cliche but are still entirely lacking in self-consciousness. At least they weren't going for a cliche look.
