|The Public Paperfolding History Project
|Issues 1 to 7 of the Magazine of the Sosaku Origami Group '67|
I have not yet been able to obtain a copy of these magazines.
There is a separate page giving information about the Sosaku Origami Group '67
Issue 2 contained diagrams for Mitsunobu Sonobe's 'Color Box', the first publication of what later became known as the Sonobe Module.
