Beautifully Bound booklet 7
After the two outstanding books ”Beautifully Bound” number 1 and 2 (aka the ”black book” and the ”red book”), a series of booklets were started: ”Beautifully Bound” numbers 3–11.
These were published by Tenseisya, Abeno Osaka
I am not certain about the order of publication, but this should be issue number 7 (1966).
