It was published in 1970, the TV series is from 1972. It's quite difficult to get inside picture of the books but it looks radically different from the TV series design.
I did a google image search...you can see a few open pages here and there. http://tinyurl.com/2c4tyqu
Yeah too bad. I really wish someone would publish a translated version of this. You can see some more Takao Saito stuff here, from another manga serie he did. Great art. http://www.survivant-kanko.com/
Oooh, it's the same artist ? I've browsed "Survivant" many times, it seems to be a good apocalyptic / survival story. I might get it someday then.
