These scans are blown up and saved in gif format, but are still legible and were done for the early web. Not much is about for settei for this show, but I've been turned onto it, so I wanted to save what could be salvaged! If I find an artbook or settei booklet, I will re-scan them.
Tezuka more than likely did not draw the settei for this show, but there is little information about who actually did. Some sources on JP Wikipedia don't say a definitive name.
