Autograph authentication for signed comics
Signed covers, splash pages, trade paperbacks and original art — MAS authenticates comic autographs from writers, artists and creators, with verifiable certification built for the modern market.
Signed comics we certify
How to spot a fake comics autograph
Mind the cover stock
Modern gloss covers and matte variants take ink differently; genuine signatures sit naturally on the surface.
Multiple signers, one book
Jam pieces with several creators require each signature to be accounted for and certified.
Sketch vs. signature
Original head-sketches ('remarques') are authenticated differently than a plain signature — know what you're buying.
Verify, don't assume
A verifiable COA you can check instantly is the strongest protection for signed comics.
Questions about comics
How do I get my comics authenticated by MAS?
Submit online at mascertified.com/submit and mail your comics in, request an Instant Verification from photos, or have items authenticated live when MAS attends a convention or signing.
Does MAS certification add value to signed comics?
Verifiable certification gives buyers confidence, and MAS-certified items are actively bought and sold and widely recognized by collectors and dealers — which supports strong, consistent resale value.
What is witnessed authentication for comics?
Witnessed authentication means an MAS authenticator was physically present when the item was signed — the strongest standard in the hobby, with no opinion or guesswork.
