Appearance Spotlight: Hydra Logo

Hydra has been around in comics for a long time. In fact, their first appearance was in Strange Tales #135, all the way back in June 1965. And in that time, their organization's logo has pretty much been the same. Here are some examples:

The comics were still using this version of the logo in January 2011 when they published Captain America: Hail Hydra #1, and continued through all five issues of that miniseries:

When Hydra appeared in Captain America: The First Avenger (July 2011), they kept the symbol mostly the same, but they did make a few changes. The most noticeable is that it's red, both to tie in to the Red Skull - who leads it in this version - and to make the color scheme closer to the Nazi Party. The other change is that they made the negative space inside the tentacles resemble gears because this version of Hydra started as the Nazi science division. (There is an interview that confirms this but I can no longer find it. If anyone has a source for this information, please let me know.)

I don't have a definite date for its first appearance (although the earliest date I can find is 2013), but this symbol has become the standard in comics. Here are some examples of that:

As you can see, while all of the pre-2011 examples are green and yellow, the post-2011 examples have started using the red from the movie as well, in some cases.
