There are at last some new photos of the White House on the official Flickr photostream. I don’t think there’s anything there that it new to us, but I’ll keep looking.
Also, I’ve been sent some great video captures from recent video tours of the WH. I’ll add some of those soon. And I just got delivery of Reilly of the White House, a 1947 memoir of a Secret Service man that promises to have some interesting tidbits.
