I've been rediscovering Mike Grell lately, particularly the first 10 years or so he was drawing comics. This is Grell's cover for the late lamented AMAZING WORLD OF DC COMICS fanzine, issue 12, dated August 1976, during Grell's run on SUPERBOY/LEGION 202-224, and 236 from 1974-1977. https://viewcomiconline.com/superboy-1949-issue-203/
