Exhibits on Oldenburg, Wesselmann offer deeper glimpse of Pop Art sensibility

The legacy of Pop Art is going through a productive period of intellectual churn, as museums, scholars and audiences reconsider the history of the Brillo Box, Ben-Day dot and Campbell's Tomato Soup can. What once seemed a cheeky and anarchic movement is now seen as a more complicated and intellectually robust chapter in 20th-century art, not so much because history is being rewritten but because lazy habits of forgetting and pigeonholing are at last giving way to dispassionate scholarship.
