I think the various Swordquest series have duplicates among them.
First, there is a series indexed called “Swordquest: Earthworld Classic Atari Mini-Comic.” I think the issue on the left is a duplicate of Swordquest #1 (the one from DC, 1982-1983).
Then, from that same “Swordquest: Earthworld Classic Atari Mini-Comic”, I think the issue on the right is a duplicate of Swordquest (the one from Dynamite, 2017-2018). I think it’s just preliminary artwork lacking the barcode.
