Howard the Avid Comic Book Collector
There’s a scene in Iron Man 2 when Tony is searching for a way to overcome his palladium poisoning. S.H.I.E.L.D. send a care package to Tony, containing many of his late father’s belongings, including a film reel that became the foundation for discovering the element that would eventually cure him.
But if you took the time to pause during this scene and go through Howard Stark’s stuff, you’ll find that he as a signed issue of Captain America Comics #1! What makes this strange and awesome at the same time is that Howard also had a hand in crafting the Captain’s shield.
