Superman is DC comics Gav.
The flash pinball and flash the superhero are not related.
Superman and Batman are the only DC pins I know of.
I would like to see a Aquaman pin if there was another DC title..I prefer the MARVEL comics personally but I enjoy the DC issues as well.
Aquaman is my fav dc hero, his story is really cool and very different to most comic book heroes...he starts out as a villian trying to destroy the humans for polluting the worlds oceans before uniting with his former foes.
