Spider-Man: Every Single One Teaser

Marvel Comics has released a new Spider-Man teaser image. It features Spider-Man in the center of a crowd of web silhouettes. The tagline is "Every Single One." Every single what? It's likely every single Spider-Man costume. The silhouette behind him looks like it's the "Iron Spider" costume from the Civil War era (you can click on the image for a larger view). But what is Marvel gathering "every single one" for? Knowing Marvel, we probably won't have to wait long to find out. In the meantime, can you recognize all of the costumes (or characters) by their silhouettes?
