Coo Coo (The Clown) - Kelloggs Corn Flakes mask (1950s) - complete cereal box

Straight from the golden age of breakfast cereal promotions, this 1950s Kellogg’s Corn Flakes box features the unforgettable “Coo Coo the Clown” cut-out mask. Kids were encouraged to cut directly from the back panel to bring the circus fun home—making complete, intact boxes like this almost impossible to find today.

The artwork captures mid-century advertising at its best: bold colors, cheerful clown design, and a full panel display that tied directly into Kellogg’s marketing push of masks and giveaways during the era. Most were destroyed once the cereal was eaten and the mask cut out—so surviving full boxes are prized by advanced collectors of cereal history and advertising ephemera.

Rarity & Value: Complete 1950s mask boxes are among the most desirable Kellogg’s premiums, especially with the iconic clown design. Surviving flat examples are extremely scarce, with most existing only as cut panels.
