Candy companies haven't kept very detailed records (Butterfinger had a "90ish" birthday), but there's one man out there cataloging sweet treats for posterity. New York-based candy collector Jason Liebig's site Collecting Candy includes an impressively detailed archive of regular and seasonal treats, 70% of which were "ungoogle-able" before he documented them.
September begins Liebig's yearly hunt for the new limited-edition Halloween candy. One day can result in 30 to 40 new treats for his growing archive documenting candy, past and present. Some spooky gems include Charms black cat and pumpkin pops from 1948, and a Japanese pumpkin pudding-flavored Kit Kat.
His extensive gallery of over 3,200 images also includes vintage candy ads; he's even consulted on shows like Mad Men and The Goldbergs to get their candy period appropriate.
