"Shutter" by Joe Keatinge and Leila del Duca is coming up on an important anniversary: Issue #25. Image Comics as a whole is also about to celebrate an anniversary -- in this case its 25th year. To celebrate these dovetailing milestones, "Shutter" will get a crossover, featuring several of the publisher's most enduring characters.

Since Image's comics are creator-owned, meaning each book's respective characters are used at the discretion of their characters, it's hard to get a crossover like this together. Well, Keatinge and del Duca did their legwork, and issue #25 of the dimension-hopping "Shutter" will feature some of the most classic characters from Image's two and a half decades of publishing.

The rare crossover event will feature everyone from Todd McFarlane's Spawn to Rob Liefeld's Glory. Other Image founders' characters will include Marc Silvestri's Witchblade, Erik Larsen's Savage Dragon and Jim Valentino's Shadowhawk. Robert Kirkman, probably the most notable name at Image these days, will be represented by his character Invincible. It's a pretty thorough lineup of characters from throughout Image's varied history.

“Image Comics is why I write comics,” Keatinge said in an official statement. “After a lot of soul-searching, I felt the best way to express my gratitude on the Image partners' momentous anniversary is to unite our characters over eating eggs and drinking mimosas.”

Del Duca added, “It's been a dream come true, drawing characters that were created and brought to life by the Image founders. "Shutter" may not have existed if it weren't for those seven men who left work-for-hire comics to make creator-owned stories. I loved spending time with their characters, incorporating them into our storyline, and having them interact with our own characters, Kate, Alain, and Alarm Cat. I had so much fun!”
