where does that 1976 date come from?
wiki says 1981 and I agree with this info

for example, gundam 1979 (between 1976 and 1981)
music releases from that period could have the starchild logo if the date was correct, but actually the op single (K08S-3003) has none whereas the 2006 release (KICM-3128) have one

edit: after some searches, I can say starchild was created around july 1981 (EPs have the logo, but LPs got the logo later -circa 1982)
