Time to take a trip to LIC for That Was Then...This Is Now on through 09.24.08 at P.S.1.

"P.S.1 Contemporary Art Center presents That Was Then... This Is Now, an exhibition featuring spectacular pieces including Leo Villareal's new LED Flag installed in the P.S.1 elevator; Apolitico, an expansive outdoor flag installation by Wilfredo Prieto; Cannone Semovente, a monumental sculpture by the late Italian artist Pino Pascali; and Lawrence Weiner's Milk and Honey, which evokes a sensuous and ephemeral dream. This group exhibition is inspired by the artistic and socio-political climate of the late 1960s, and features artists united by the desire to mobilize art as a means of change. Divided into three iconographic themes - Flags, Weapons, and Dreams - That Was Then...This Is Now places these representations as central to artists' collective aspiration towards progress.

The Flags section presents artists' interpretations of the American flag and explores elements of nationality, patriotism, and iconography, and the debates invoked by these concepts. Spencer Sweeney takes a police car, an emblem of authority and control, and literally inverts it into a monumental banner. Utilizing the colors of the Pan-African movement, David Hammons champions the United States' underrepresented minority. Jasper Johns, perhaps the most well-known for his representations of the flag, has returned to this theme throughout his career and considers this loaded symbol as a graphic form." Read more here.
