GHOST OF FRANKENSTEIN was released in Japan on October 4th, 1949.
So obviously in Japan the MPEA logo does not guarantee that the poster is from 1946-48.

It started in the end of 1945 in German, Japan and a few other places. Obviously it kept going until at least October 1949, based on your info.
But in Germany, many movies were released by MPEA a year or more prior to the official release to regular German theaters, so it is possible the same was true in Japan.
