Looks like I should have been more meticulous about the care and upkeep of the discs. Most of them are fine, but this is what the last two look like.
Literally crumbling. It's all old photos of my parents when they were kids, so I'm pretty sure a lot of others have them to share with me, so in the end I should be fine.
Just know this: if you burn a disc in 2002, you should probably replace it before 2017.
