The price of Campbell's soup began its dramatic rise after Warhol's record-breaking sale of Campbell's Soup Cans in 1970. (https://en.wikipedia.org/wiki/Campbell%27s_Soup_Cans)

Although back then you could buy Campbell's Soup Cans (the painting) for just $60,000. In 2022, a famous Warhol painting went for ~$195,000,000.
