In 1906, Kellogg’s needed a clever way to get people excited about their new Corn Flakes. The solution? A wink.

As part of a cheeky marketing stunt, ads instructed women to wink at their grocer to receive a free box. In an era when winking could raise eyebrows, the campaign stirred plenty of buzz—and cereal giveaways.

The flirty gesture wasn’t just for fun. It got people talking, turned heads in grocery stores, and helped Corn Flakes land on breakfast tables across the country. One wink at a time, Kellogg’s became a household name.
