For those who think that the political controversies over the F-22 and F-35 programs are something new, the XB-70 program is testament that they aren't. The Valkyrie efforts were an on-again-off-again see-saw. NAA got the go-ahead to build the plane in 1959, then it was scaled back, accelerated, and then cancelled, with the prototypes redesignated as research aircraft. Two XB-70s were completed and flown, with a third (a YB-70, actually) cancelled while under construction.
The St. Petersburg Times, when they used an image, would typically glue a copy of the actual newspaper edition to the back of the file copy, to show that it ran. This photo has none, so presumably it wasn't published, at least by that paper.
Incidently, if you look closely at the roof structure in this recent Global Hawk rollout photo, you'll recognize that the hangar which saw the birth of the XB-70 continues to see new planes develop!
