Had Tony Stark been wearing the Iron Man Symbol & Image Dog Tag Necklace then it probably would have protected his heart and he would have never become Iron Man...which means you could have become Iron Man! I mean, who doesn't want to be Robert Downey Junior, err, I mean Tony Stark! The double-format Iron Man Symbol & Image Dog Tag Necklace has the Reactor symbol on one while an image of ol' Tin-head is on the other. Who is Iron Man? YOU ARE IRON MAN!
