McDonald's Secret Archive Holds Decades of Fast-Food History
Inside McDonald's Chicago headquarters lies a hidden archive preserving 71 years of company history, including artifacts from its founders and marketing campaigns.

McDonald's maintains a discreet archive at its Chicago headquarters, safeguarding 71 years of the fast-food giant's history. The collection features a wide array of items, from oversized novelty Big Macs and a four-eyed Grimace mascot to shelves of Happy Meal toys and even a Travis Scott Chicken McNugget pillow.
Senior archive manager Mike Bullington, who has overseen the collection for 21 years, identifies Ray Kroc's 10th-anniversary ring as the most valuable item. The archive also houses Kroc's original Multimixer milkshake machines, used when he first partnered with the McDonald brothers in 1954.
While not open to the public, the archive serves as a business resource for internal teams, aiding in research and development. Bullington cited its use in updating training materials for products like the Quarter Pounder. "It’s not a closet of curiosities," Bullington stated, emphasizing its role as a business asset.
A notable item that remains elusive for Bullington is a 1983 nine-piece Chicken McNuggets box, preceding the chain's switch to 10-piece packaging in 1993. Bullington has since acquired the six and 20-piece versions, but the nine-piece remains his sought-after "white whale."
The collection represents a tangible link to McDonald's evolution, preserving key moments and memorabilia that chart its course from a small hamburger stand to a global fast-food leader.
