Former Washington Post chief Don Graham posted a goodbye to his old paper's building on Facebook Monday night. "This probably was my last day at 1150 15th Street after 43 years," he wrote. "The Post seems to be in wonderful shape under Jeff Bezos, Katharine Weymouth and Marty Baron."

Graham Holdings Company, the former Washington Post Co., is moving from Washington, D.C., to Arlington, Virginia.

GraHoCo offered items from its art collection to Post employees last month, with proceeds designated to TheDream.us, a scholarship fund for undocumented students that Graham founded.

The Post won't be in its 15th Street building for much longer either; it plans to move to a building with a serious Dan Brown connection.
