The case
Every Gen X kid saw this label a thousand times: on the waistband of a three-pack, on the tag your mom checked for size. And a striking number of people can describe, in detail, the wicker horn the grapes and apples tumbled out of.
Fruit of the Loom has stated flatly that no version of its logo ever had a cornucopia. Trademark filings going back decades show fruit, leaves and, in older marks, a ribbon. The horn lives in memory only.
Why our brains do this
A cornucopia is the classic way to draw a pile of fruit, so the mind supplies one. Once the image has been "corrected" a few times in memory, it feels like something you saw.
