Captain America, the Hulk, Fantastic Four... If you read superhero comics, you've probably liked a character created or co-created by Jack Kirby. He made the battles of superheroes like Thor feel larger than life but he also grew up fighting in the streets of New York City's gritty Lower East Side neighborhood. And he made an awesome, rarely-seen comic about it.

Last week, a pop-up museum honoring Kirby showed off some of the legendary artist's work just a few blocks away from where he grew up. Being a big Kirby fan, I went over to the Kirby Pop-Up Museum to see the blown-up artwork on display and talk to organizer Randolph Hoppe about Kirby's life. And if you love Kirby, too, share a your favorite piece of his artwork in the comments below.
