A very cool haul. That Amazing Heroes cover might be a back cover or alternate artwork for a Marvel Comics Presents from that era. I know that all 3 were in several issues at that time (in separate stories). My Archie hunts are for the 25 cent issues. A lot of what I pick up (cheap) are 25 cent covers. ••• Looking forward to the next 2 parts.
Yeah Blackstar is Starfire's sister in TTs, but with one 'r'. I think Archie being able to laugh at himself is a good thing, his ego is not easily hurt but maybe I am thinking too hard lol Some lovely books mate, enjoy your haul
