“It’s Not Butter!” - Classic Advertising Parody Cartoon #1959800 (License: Personal Use)

This satirical cartoon depicts a teacher emphatically writing variations of “I can’t believe it’s not butter!” on a chalkboard, as students-including a bewildered cow-watch with growing skepticism. The scene exaggerates how deeply branded slogans embed themselves in public consciousness, turning advertising into absurd ritual. The visual humor lies in the repetition, the teacher’s fervor, and the anthropomorphized cow questioning the claim.

Used on marketing, advertising history, or pop culture blogs to illustrate meme-like brand saturation or parody campaigns; matches user intent for humorous takes on advertising tropes or nostalgic brand references.
