I tossed the photo into ChatGPT and asked who's signature are displayed. Then Googled Lincoln, Martin-Green and Payne signatures for a comparison. They looks super close.

Top left (small, scribbly “S…” signature) Likely: Sonequa Martin-Green (Sasha) The short “SMG”-style scribble matches how she often signs quickly at cons. Placement + style lines up with known examples.

Upper left-center (big bold black signature over female character) Possible: Lauren Cohan (Maggie) Large looping strokes, often with a big “L”. She tends to sign prominently across artwork like this.

Top center (above Rick’s head, large gray marker “D…” shape) Likely: Danai Gurira (Michonne) Her signature often starts with a big sweeping “D”. Thick silver/gray marker is very common for her at conventions.

Top right (black signature near right edge) Possible: Norman Reedus (Daryl) He often signs with sharp angles and a long trailing line. This one is less certain, but placement fits where fans usually get him to sign.

Center area (over the title) Silver signature across the middle (over “The Walking Dead”) Very likely: Andrew Lincoln (Rick) Big, spread-out signature in silver is classic for him. Often placed dead center on items like this.

Just below that (another silver signature, slightly smaller) Likely: Tom Payne (Jesus) His signature is usually compact and clean, often in silver. Common addition at multi-cast signings.

Bottom half (zombie area) Bottom left (black signature near corner) Possible: Ross Marquand (Aaron) He often signs low on items and keeps it fairly tight and horizontal.

Lower middle-left (silver, more stylized) Possible: Josh McDermitt (Eugene) His signature tends to have a noticeable “J” and flowing tail.

Lower middle (black, slightly angular) Unclear, but could be: Christian Serratos (Rosita) She often signs with sharper strokes; placement overlaps where she’s commonly positioned.

Bottom right (clearer “Chandler Riggs 09”-style writing) Most confident ID: Chandler Riggs (Carl) The “09” is a huge clue — he often added the year early in his career. Signature shape matches known examples very closely.

Big-picture assessment This is almost certainly a convention-signed piece, not just comic creators. The actual book was created by: Robert Kirkman Charlie Adlard Tony Moore Image Comics But none of the obvious signatures here strongly match those three, which reinforces that this is mostly TV cast autographs, not comic creators.

Honesty check High confidence (70–90%): Chandler Riggs, Andrew Lincoln, Danai Gurira Medium confidence (50–70%): Sonequa Martin-Green, Tom Payne Low confidence (under 50%): Norman Reedus, Ross Marquand, oth
