Shepard Fairey, who for years was an artist whose work was seen primarily on streets, now has his first museum retrospective, at the Institute of Contemporary Art in Boston. Mr. Fairey may be best known for his Obama Hope poster.

"Obey Revolution Girl" (2005). A resourceful sampler and recycler of found imagery, Mr. Fairey has incorporated graphic motifs and compositions from the Russian Constructivist Alexander Rodchenko, Chinese Communist propaganda, American Social Realism, Islamic patterns, neo-Classical-style postage stamps and stock certificates.

He has also borrowed from the Pop Art of Andy Warhol, seen here in a portrait, "Obey Andy Warhol" (2004).

"Obey Middle East Mural" (2009). Among his most compelling works are those revolving around images of beautiful, rifle-toting women and children from third world countries, with flowers in their gun barrels.
