Yes, those are the ones I read in 1967. We must get Taz to add those to The Art Gallery collection. They also wore out after I gave them to my mother and brother to read. I've gone through two other sets since then and just bought the movie cover set to replace my working set for use on P-T.
That same side by side mural is also the artwork on the blue hardcover of Donald Swann and Tolkien's The Road Goes Ever On.
The emus must have been a prescience that the movies would be made in the Southern Hemisphere and the artist couldn't draw a kiwi or missed the venue by a couple timezones.
