The greatest thing you're likely to see today, or, heck, this week, is "ABC Superheroes" by graphic designer Fabian Gonzalez. It's exactly what the title, and the above image, suggests -- and it's pretty wonderful. Most of the letters and corresponding superheroes are easy to figure out -- A is Aquaman, L is Lion-O, S is Superman -- but a few, like M and U, take a little thought (Mandrake and Ultra Boy, if you're wondering). G and X are by far my favorites.
If you like "ABC Superheroes" half as much as I do, you're in luck: Prints are available at Society6, where you can see the full image.
