Costume Spotlight: Captain America's Armory

In Captain America #12 (July 2019), we learn that Captain America has an armory of sorts. We've seen this with characters like Iron Man and Batman, but it's a first for good ol' Captain Rogers. In doing so, however, we're treated to a variety of costumes from throughout his history, including a few I wouldn't exactly expect to see.

On the far left is, naturally, the costume from his first appearance in Captain America Comics #1 (1939). But more intriguing is the one next to it. This one isn't from the comics at all, but instead, the 1979 tv movie, and its sequel, Captain America II: Death Too Soon (also 1979).

These movies featured a very different Captain America more inspired by Evel Knievel. There was still a tie to the 40s, though it was because Steve Rogers's father was a famous government agent of the time, also known as Captain America. And there was still a super-soldier serum, though it was more of a super-steroid derived called FLAG (Full Latent Ability Gain) from Steve's father's own physiology. Everything else about the story is different.

The suit after that is the Commander Rogers outfit from circa 2010, but the next two are VERY interesting. The first is Captain America's World War II uniform from The Ultimates #1 (January 2002)...

...and the next is his modern outfit from the same issue. Which means they're from Ultimate Marvel, an entirely different comics universe. What's going on here? Are they relics from the merging of Earth-1610 and Earth-616 in Secret Wars? Or is there some other explanation?

Finally, there's this one. I can't totally be sure it belongs on this site, but I'm including it to put it to the masses. It looks like it's probably from some animated project, but I can't figure out which one. So what say you? Is this suit from some tv or movie, maybe a toy line or Hostess ad? Is it from some comics alternate reality? Or is it just from some run-of-the-mill comics storyline and I simply don't recognize it?

Let me know if you know!
