Carl Fredrik Reuterswärd was a central figure in Sweden and internationally in the post-war art world. Only Öyvind Fahlström is likely to have had greater significance on the global art scene, and no other Swede is likely to have had the same international network as Reuterswärd, ranging from artists such as Marcel Duchamp to critics such as Susan Sonntag. Well-read, intellectual, articulate, playful and a virtuoso, he created his most important works in the early 1960s. Games, indicative of the harvests of chance, cigars in various formats and the use of repetitive pictorial elements predating Warhol were all created between 1961 and 1963. He then took his famous vacation, during which he experimented with lasers over the rooftops of Paris. Later, he created various identities; Kilroy and the art dealer Pratt-Müller are just some of the better-known examples.
