COMICS

Pop-up Kirby Museum

Jack Kirby, co-creator of many of your favorite superheroes — Captain America, Thor, The Fantastic Four, Iron Man, X-Men, just to name a few — grew up on the Lower East Side in the early part of the 20th century, so it’s only fitting that a pop-up Kirby Museum would set up shop in the neighborhood this week. Stop by Monday for opening night with Rand Hoppe, Tuesday at 7 p.m. for a talk titled “Jack Kirby and the Auteur Theory of Comics” and Sunday at 5 p.m. for a chat with James Romberger.

(Monday through Sunday, noon-7 p.m. daily, FREE with suggested donation of $2, Kirby Museum, 178 Delancey St., kirbymuseum.org)
