In this Thursday, June 28, 2012 photo Scott Stephenson, the director of Collection and Interpretation looks under the scale model of Gen. George Washington's sleeping and office tent, to study and mount the original canvas marquee for a museum in Philadelphia. This artifact and others hidden treasures will remain under wraps in their anonymous location until late 2015, when The Museum of the American Revolution is scheduled to open in Philadelphia's historic district.
