I've seen that photo in Ben Rich's book, "Skunk Works". It that it was supposed to be the one moved onto permanent display at Beale AFB in
California. But, I have also seen a more likely candidate, Blackbird 958 now on display at Robins AFG in Georgia:

There used to be a very similar photo on the website for the Robins Museum of Aviation but I can't find it anymore.
