Comments
One of the few conscious changes Ralph Montagu made in the Tenth Anniversary Special reprint was to the title sequence on pages 2 and 3, pictured above. The reprint edition is at the bottom of the image and clear differences are apparent between this and the original edition above.
The reprint sequence was made from a new set of electronic screen grabs, in 1973 this would have been prohibitively expensive (and time consuming) so the original only featured about 7 different frames, each being repeated several times whereas the new version is now a continuous sequence of consecutive images.
