hmmmm... I dont think that is right. Where are you getting that info from? Bob Kane created Batman and Iron man was created by Stan Lee and Jack Kirby as far as I am aware...
You know come to think of it I "heard" these two were created by the same dude. A the guy I heard it from wasn't really a reliable source...but, he said he heard that this artist had passed away. Couldn't be Kirby tho. I got this "info" long after he passed. ???IDK
