hehehe. So cute! I saw this when DC Nation first shared a month ago. Thanks, Tony! Love the expressions. Supes looks a little naughty as if he is about to reel Diana in!!! heheh. I think that was a little nod for the SMWW crew given Tony was on the book too.
But yeah as Love Star says this is DC using their popular duos because the public recognize them and will pay attention to them. Those two are used in marketing. Just like when Clark and Diana were used for Land Mine Awareness and many other stuff up to games like HeroClix or Dicemasters and lots of other merch. Been seeing many couples online using SM and WW masks too.
