Here's a cute little app that quizzes you on (grossly simplifiedm, 12-pixel) versions of Superhero Chest Symbols
Bear in mind that what it's showing you is 12 pixels representing the chest and waist of the hero/villain. Don't try and interpret it as a shot of the logo itself, or just part, or it'll confuse you.
For what it's worth, I scored 20/21 (I got the first one wrong because I wasn't sure what I was supposed to be looking at).
