Obviously some time between the first Russian snapshots and the Apollo programme, but when did we have the first complete map?

I have an atlas of the Universe dated around 1970 -71 that has all the far side features named. So obviously there had been time for the IAU to okay the Russian names for major features

Almost the entire Moon was mapped photographically by Lunar Orbiter IV and V in 1967, which were put into polar mapping orbits after the first three fulfilled the initial mission of surveying potential Apollo landing sites. There was a small area near the south pole and beyond the Mare Orientale piece of the limb as seen from Earth for which developing or timing problems meant there was no imagery. The section was called Luna Incognita (or less formally the Sea of Unsatisfactory Photography), for which there was a concerted effort to improve matters from Earth during just the right illumination and libration. That gap was finally filled by Clementine in 1994 .
