Aikido book from the 50's or early 60's?
I just inherited several aikido books from my grandfather who practiced aikido from 1957 to 1992 in hakalau hawaii ,he passed away in 2005." Ki in daily life" signed by Koichi Tohei sensei ,"How to develop Ki " signed by Koichi tohei and Koretoshi Maruyama sensei and a third book . This 3rd book i have never seen before ,The tiltle just says "Aikido" in japanese,it has a picture of 2 aikidoka practicing shizumi otoshi or aikido knee drop on the cover ,its is all in japanese ,the pictures have koichi tohei doing taiso and techniques ,the date on the back of the book says 1959and the most interesting part is that there is a page that is actually signed by O sensei next to his picture. I verified the signature with my sensei but have no idea about this book . I tried looking on the internet and have no leads .
Does anyone have any information on this book or ideas where i can find more info . Thank you .
