Looking for titles similar to Yaji and Kita

[OisE]

I am looking for titles similar to New Journey of Yaji and Kita.
The title must not be another title from Hasegawa Machiko.

Any idea?

Thank you for your help.

You mean old books from the 50s or something else?

From this time and/or more recent too.

I haven't read that work, only the description and nothing occurs to me other than checking tracker sites using the data filter. For example, the year Jungle Taitei started. There's good period manga in the 70s and 80s, but I have no idea that early. Those were the years of Astro Boy too!
