The 1973-1974 anime series Zero Tester ran for 66-episodes across two different names and was previously slotted for some new DVD collections in Japan.
Based on the original work by Yoshitake Suzuki, it was directed by Ryousuke Takahashi with character designs by Munehiro Minowa.
The first set is coming up in a week and we now have artwork for that and the second collection at the end of next month.
