The U.S. Department of State Bureau of Overseas Buildings Operations’ Office of Art in Embassies is launching a traveling exhibition as part of a year-long initiative for its 60th Anniversary called the Democracy Collection. The exhibition, “A More Perfect Union: American Artists and the Currents of Our Time,” opens to the public on May 25th at the Acropolis Museum in Athens, Greece, moves to Lisbon, Portugal, in June, and arrives in Geneva, Switzerland, during the United Nations (UN) Human Rights Council Session on June 29.

At each location, U.S. embassies will host art-filled public diplomacy events on democracy. U.S. Ambassador to Greece George Tsunis will host Partners in Democracy, a symposium featuring emerging voices and thought leaders—among them documentary photographer Platon whose portraits of world leaders grace the covers of Time and other magazines—who will discuss the current challenges democracies face.
