Photo to mark the 75th anniversary of the US National Science Foundation, with 250 staffers posed to the side of the building in a non-official photo taken on the staff time by an amateur photographer so that the senior management who were not allowed to be present could allow this short event. The building is about 18 stories tall, the meeting area is all bright green grass and there are other buildings and a cluttered landscape around the people and building, with cloudy skies.
