Bingo, Tank. You and ChaaBreh nailed it. I was looking around Clark's apartment in my head trying to find things that didn't quite match up and saw that hanging on the wall. I knew I had to include it.
I'd love to turn this into an Elseworld's Graphic Novel, but it'd have to be Curt Swan to draw it just so it'd reconcile with the pictures in my head.
Whenever I write a few scenes I have the urge to dig out some 1970's classic Superman and give them a read.
This whole experience may trigger a second childhood...well, possibly a third one anyway.
