This is a 1,000-sheet stack of Post-It type note sheets that I got wayyyy back in the day, over 20 years ago, as a piece of Nikon "swag" as part of their Advanced Systems Specialist sales certification nonsense. I've kept this doggone stack of paper around for a loooong time, in a plastic bag. I took a shot of it with my iPhone, then Instagrammed this frame.
