Howard Stark’s memorabilia
The further we get into the Avengers movie series, the more we learn about the history of the characters and of S.H.I.E.L.D. One of the most intriguing characters we get to hear more about is Tony Stark’s father, Howard. He was a billionaire inventor who was involved in the early days of the Strategic Scientific Reserve, which later became S.H.I.E.L.D.
During a scene in Iron Man 2, we see Tony Stark looking through a trunk of his father’s belongings. Amongst the papers, film cans, and other memorabilia we see an original Captain America comic. His dad obviously stayed a big fan even after Cap disappeared without a trace.
