I had one of these but they didn’t show mine. The picture sucked anyway. If you’re wondering about the weird colors, they wanted to make them look like 1920s baseball cards. Eclipse published them which is why so many people in the deck had worked for Eclipse at some point.
As for why the pictures were the way they were, that’s how they were sent in by the creator’s themselves. Except for some of the older guys, they probably used images on file somewhere. Because Wally Wood and Walt Kelly were dead at that point.
