Crown Authentication has examined the autograph present on this 2025 SMZ Comics Metal Trading Card (No. 10, numbered 10/10), attributed to artist Eddie Nuñez. The signature appears in light blue ink at the lower center of the brushed metal card face, rendered with a fluid, sweeping formation characteristic of the signer's known style. Ink examination confirms this is a live ink autograph — physical indicators including darkened overlaps at stroke intersections and visible variation in ink pressure and density across the signature are consistent with a genuine hand-signed application rather than a printed or facsimile reproduction.
