CGC Announces Private Signing with Geoff Johns and Jason Fabok

Posted on 4/15/2026

Writer Geoff Johns and artist Jason Fabok, the powerhouse duo behind Ghost Machine's Rook: Exodus, and DC’s Darkseid War and the critically acclaimed Three Jokers, are joining forces for an exclusive CGC Signature Series Private Signing.

CGC Signature Series is pleased to announce an exclusive Private Signing event with comic book writer Geoff Johns and artist Jason Fabok! Collectors can submit both comics and cards to this event.

Geoff Johns is an award-winning and New York Times bestselling writer, film and television producer, showrunner, and entrepreneur known for re-imagining superheroes and other iconic mythologies, past and present. Johns is best known for his work on properties such as Green Lantern, Aquaman, The Flash, Superman, Batman, Justice Society of America, and, most recently, the creator-owned hit series Geiger, currently being adapted for television at Paramount.

Since the beginning of his creative career, Johns' hallmark has been writing heroic and inclusive characters, including teenage hero Courtney Whitmore aka Stargirl, inspired by his real-life late sister; the Shazam Family, which he re-imagined into a diverse modern family of today; and the first Arab-American Green Lantern, Simon Baz, as well as the explosive multi-colored Lantern mythology that defined his decade-long bestselling Green Lantern run, among many, many others.

Johns’ most recognized work in television is the critically acclaimed Stargirl series, which he created and ran. Some of his film credits include Wonder Woman (executive producer), Wonder Woman 1984 (also co-writer), Aquaman (also story), and Shazam! (executive producer), based on his graphic novel with longtime collaborator and modern legendary artist Gary Frank.

In 2023, Johns co-founded Ghost Machine, the first-of-its-kind creator-owned company. This groundbreaking collective includes some of the industry’s most legendary writers and artists, disrupting the old industry model by giving ownership to its creators, and paving the way for them to retain creative control and financial participation. Johns and artist Bryan Hitch’s creator-owned series Redcoat is being developed as a feature film with Chuck Roven and Atlas Entertainment, and Johns writing the screenplay.

Born in Detroit to a Lebanese father, Johns was honored with his own permanent section at the Arab American National Museum in Dearborn, Michigan.

Jason Fabok is a professional comic book artist, creator, designer, and illustrator mostly known for his work for DC Comics and Ghost Machine. After being mentored by comic superstar David Finch, whom he worked with on Batman: The Dark Knight, Fabok has gone on to contribute to some of DC’s biggest titles: Batman, Justice League, Detective Comics, Suicide Squad, Man of Steel, and Batman Eternal. In 2016, he joined forces with writer Geoff Johns on Justice League to deliver the critical and commercial hit The Darkseid War. In 2019, Fabok won an Eisner Award for Best Short Story for his work on Swamp Thing’s The Talk of the Saints. In 2020, Johns and Fabok teamed up again to deliver the massive hit Batman: Three Jokers, which has gone on to become one of DC's highest-selling books of the decade.

In October 2023, Fabok joined forces with Geoff Johns, Bryan Hitch, and Gary Frank to form a brand new creator-owned company called Ghost Machine. The goal of Ghost Machine is to publish creator-owned comics in partnership with Image Comics, and to help the participating creators benefit from the development of its intellectual properties. Fabok and Johns created the sci-fi action-adventure series Rook: Exodus with help from colorist Brad Anderson and letterer Rob Leigh, and released it in 2023 to critical and commercial acclaim. Outside of comics, Jason has designed action figures, statues for Prime 1 Studio, coins for the Canadian Mint and other collectible products. He lives in Southern Ontario, with his wife and kids.
