Os Gemeos are set to open their first solo museum exhibition in the United States on August 1 in Boston. The Institute of Contemporary Art will play host, but won't be the only space in Bean Town to benefit from the twin's trademark style. The brothers are also painting outside at both The Revere Hotel and on the Dewey Square Air Intake Structure between Summer and Congress street. They gave us the first look at one of the murals last night on Instagram. Check it out.
