From the Fabulous '40s through the Swinging '60s to now, Pop Art's style has endured.

Earlier this year, the Allentown Art Museum explored the beginning of Pop Art's story in "British Pop Art Prints," which revealed how American Pop Art grew from a movement that started in London in the late '40s and early '50s by British artists such as Richard Hamilton and Eduardo Paolozzi.

Then came the Americans — Andy Warhol, Jasper Johns, Roy Lichtenstein and Claes Oldenburg — who rose from relative obscurity in New York to become some of the world's best-known artists, and had an influence on everything from design to fashion and film.

The museum explores that story in "American Pop: The Prints," an exhibit of works from the museum collection and Muhlenberg College that serves as a companion exhibit to "Robert Indiana from A to Z," a retrospective of work by one of the Pop movement's founding fathers.
