Hergé was both a marvelous storyteller and artist. His drawing technique — the clear line, where figures are created with outlines of equal thickness and filled in with uniform colors — was not only adopted by other comic-book stars, Asterix’s creators, for example, but also attracted modern artists. Balthus and Giacometti were avowed admirers, while Warhol recognized that “Hergé has influenced my art as much as Disney. [It has] a great political and satirical dimension.” Hergé returned the compliment. Two of Warhol’s portraits of the Belgian cartoonist hang in the museum.
