Stephen M notes that the JFK Library has released 1000+ digitized photos of from the Kennedy administration, including many never-before-seen images. There are some great ones of the China and Vermeil rooms and some rooms upstairs and even on the third floor.
And if you figure out how we can download the full-sized image, please post a comment here. These are public domain photos. American taxpayers paid for them. We should have them in their highest-quality form.
