During late 1950's helped launch an alternative to Abstract Expressionism in USA. His appropriation of immediately recognizable imagery: American flags, targets and numbers resulted in a more public, apparently less introspective approach than was prevalent, and his work was distinct for being premeditated, ironic and detached.

During 1960's Johns turned to more private imagery - but his art still held a central position in terms of its effect. The impact of his work influenced the most important artistic developments of the 60's and early 70's in the USA.

Since mid 70's, Johns concentrated on history of art and what it means to be an artist. Juxtaposing abstract patterns, hidden references and familiar objects, he reached new levels of complexity in canvases that rank among the most beautiful created in our time. This work in 1980's was based on his more expressive personal imagery.
