Andy Warhol’s New Coke drawing depicts a Coke can spilling over, which makes the purpose of the image ambiguous. It is not explicitly an advertisement trying to sell Coca-Cola. The debut of New Coke was highly contested, as consumers complained that the reformulation of the popular drink was a let-down in comparison to the original flavor. Warhol also created New Coke (see F. & S. IIIB.44) screenprints in color.
