2019 marks Comic-Con’s monumental 50th event—known officially as Comic-Con 50—and what better way to celebrate than with an extra-special Souvenir Book cover by one of comics’ top artists?

Comic-Con is pleased to reveal this year’s cover, penciled by the great Jim Lee—with inks by Scott Williams and colors by Alex Sinclair—featuring 13 of comics most popular characters. Sure you’ve seen Superman, Batman, and Wonder Woman together before, but have you seen them with Spider-Man, Captain Marvel, Black Panther, Hellboy, Spawn, Michonne from The Walking Dead, and all four Teenage Mutant Ninja Turtles—Leonardo, Raphael, Donatello, and Michelangelo? It’s the team-up fans have been dreaming about!

It was DC Comics publisher and chief creative officer Jim Lee’s idea to feature all of these earth-shattering heroes bursting from the San Diego Convention Center lobby to save the world in a one-of-a-kind piece of art the likes of which has never been seen before.

Jim had this to say about working on this year’s cover: “The honor was mine getting to do this historic cover for the world’s preeminent pop culture event. What an amazing 50 years!”

“Comic Con was the start of it for me and from my very first Con back in 1987, it’s been a huge part of my life. I’ve watched it transform the business and usher in a world I don’t think any comic book reader back in 1987 would ever have imagined to come to be.

“Thank you, Scott and Alex—you two continue to elevate and enhance everything you guys touch and this cover is a testament to the teamwork that we have forged and the sheer talent you bring to every project.”
