While they've always been crack-level addicting, Oreos have gone through a ton of changes over their century of existence. The cookie design has been tweaked, the recipe's been altered (goodbye, lard), and of course, the packaging has been through a million updates. To give you a better sense of Oreo's storied history, we grabbed a few vintage photos of the snacks from the company peeps themselves. One picture's so 1920s it's illustrated, while another is so '90s, you can practically hear the swish of Zubaz pants as you stare. Check 'em all out below, then let us know which brand evolution you'd like to see featured next in the comments.
