I just picked up this neat little photograph advertised as WPA (Works Progress Administration) workers at Camp David. The back of the photo says "May 1, Bldgs at Thurmont Natl. Park Service 1937" along with a handwritten note saying it was at Camp David. Of course, in 1937 it was not known as Camp David and this may not have been taken there. The WPA did erect many buildings on the National Park property and this is certainly a very interesting photo. At first glance, it looks like a building being put up, but a closer look shows a lot more activity.

The WPA was the largest and most diverse of the New Deal public works programs. It was created to alleviate the mass unemployment of the Great Depression and by the time it was terminated in 1943, the WPA had put 8.5 million Americans back to work.
As can be seen, there are piles of sawn lumber on both sides of this view and a couple of men can be seen in the back corner standing on some wood. There are what look like rafters in the foreground and some sort of scaffolding down the center of the framing.
