The dual autographs on this Crocodile & Mihawk ST25-003 card are stylistically consistent with live ink examples attributed to John Swasey and John Gremillion. The silver/white autograph attributed to John Swasey displays a broad, loose, fast-moving signature structure consistent with known John Swasey signing examples. His autograph commonly presents with rounded opening motion, connected mid-signature strokes, and a simplified compressed finish rather than fully legible block-letter formation. The submitted signature shows the same type of fluid, convention-style marker movement, with natural pressure variation and uninterrupted stroke flow. Its placement near the Crocodile side of the artwork also supports the attribution, as live voice actor autographs are commonly placed over or near the character represented by the signer. The gold autograph attributed to John Gremillion is also visually consistent with known John Gremillion live ink examples. Verified/third-party authenticated Mihawk items attributed to Gremillion commonly show a large, sweeping first-name structure followed by a longer, connected surname flow with broad lower strokes and an extended finishing motion. The submitted gold autograph shows a similar wide horizontal layout, layered stroke movement, and elongated finishing sweep. The autograph is positioned near the Mihawk portion of the card artwork, which is consistent with character-aligned dual-signature placement. Both autographs display characteristics of live marker/paint-pen application, including surface-level ink presence, stroke overlap, variable opacity, and natural movement across the glossy card surface. The signatures do not appear to be part of the printed card design. The use of two different marker colors, character-side placement, and signature flow are consistent with live signing presentation for dual voice actor signed One Piece cards. Based on visual review, signer attribution, character placement, and comparison to known public examples, the autographs are considered stylistically consistent with John Swasey for Crocodile and John Gremillion for Dracule Mihawk.
