CGC Signature Series is pleased to announce an exclusive Private Signing event with comic book artist Mike Mayhew! Mayhew has done exceptional work for publishers like Marvel, DC and Dynamite.
Mayhew specializes in photo-realism and intense rendering of dynamic subjects, using an approach that ranges from state-of-the-art digital techniques to traditional watercolor and acrylic painting. He has worked on many variant covers including titles like Star Wars, The Amazing Spider-Man, Deadpool, X-Men and Vampirella. Recently, Mayhew created stunning covers for the series G.I. Joe: A Real American Hero and The Mandalorian.
CGC must receive all submissions for this event by July 10, 2026. The deadline for international submissions is two weeks earlier than the US deadline to allow time for delivery.
If the CGC Private Signing needs to be rescheduled, CGC will securely store all submissions in its vault until the event can be held.
After the submitted cards are signed, CGC will grade and encapsulate them with an estimated turnaround time of six weeks. After grading and encapsulation, the collectibles will be shipped back to their owners.
The CGC Cards Signing fee for Mike Mayhew is $65 per item and includes:
Mike Mayhew’s signature
Estimated turnaround time of six weeks for CGC grading
Encapsulation with the iconic yellow CGC Signature Series label
