Crown Authentication has examined the autograph present on this 2025 SMZ Comics Metal Trading Card No. 10, signed by artist Eddie Nuñez. Ink examination confirms a live ink autograph, evidenced by darkened overlaps at stroke intersections and varying ink pressure and density across the signature — physical characteristics inconsistent with a printed or facsimile reproduction. The bold, gestural signature appears in vivid pink ink in the lower-right area of the card surface, consistent with Eddie Nuñez's known autograph style, numbered 10/10 in the edition.
