This one appeared as the back cover of Fantagraphics' Zero Zero. Mid '90s, but I don't remember the exact year, only that 100 MB was considered to be a lot of memory back then. So to bring this up to date you'd have to include cell phones (20); digital devices (50); DVDs (1000); I forgot Sports Memorabilia (100 lbs.). I'm sure there's other stuff I've forgotten, but memory--the biological variety--is maxed out.
