When moving, I ran across a box of old Sports Illustrateds. Some of them had Dawgs on the cover, like #34. I mulled about keeping some of them, but I realized they had been in that box in the basement for decades, so out they went. If you have something in a box for decades, it's probably not something you "need" or even want.
I also accumulated a lot of photos, many of them slides, I used to shoot color positive film a lot, in those rotary slide racks. They all went to trash, same reason.
Today of course a photo costs nothing to shoot with a camera. Back then a print was fairly expensive unless you did it yourself. I did B&W a fair bit at one time. But, we have all these photos now on our computers and phones and rarely look at them.
