The letter the Campbell Soup Company sent Andy Warhol
The letter the Campbell Soup Company sent Andy Warhol concerning his famous paintings of their soup cans in 1964.
Following the success of Andy Warhol’s 32 Campbell’s Soup Cans, a product marketing manager at Campbell’s, William MacFarland, decided to express his admiration for the Pop artist’s work by sending him this fan letter, along with a couple of cases of tomato soup.
Can you imagine that happening today? There's simply no way. Instead, you'd get a legal nastygram cease & desist, with all sorts of claims about trademark and a likelihood of confusion and demands to hand over the paintings immediately. And then people would defend Campbell Soup, saying they "had to" defend their trademark. How quickly the world has changed.
