Panini Phoenix DK Metcalf 'Thunderbirds' Error or Custom Trading Card

This is a standard-sized trading card (2.5" x 3.5") featuring a violet/purple holographic foil finish. The card is titled 'THUNDERBIRDS' at the top and identifies the player at the bottom as 'DK METCALF' for the 'STEELERS'. The card features a high-gloss, premium cardstock construction with a metallic foil treatment that reacts to light. The central graphic depicts a football player in a black and yellow Pittsburgh Steelers uniform (wearing jersey number 4) with stylized silver/white wings extending from behind the player and white lightning bolt motifs flanking the edges. Notably, this item appears to be a manufacturing error, misprint, or a custom-made 'fan art' piece, as DK Metcalf is a prominent wide receiver for the Seattle Seahawks and has never played for the Pittsburgh Steelers. The imagery actually shows Steelers quarterback Justin Fields, further indicating a significant data error on the card. The card is currently housed in a protective soft sleeve inside a rigid plastic top-loader, which has preserved its condition. The corners appear sharp and the edges clean, with no visible surface scratches or 'silvering' on the foil edges. The centering seems slightly shifted toward the right margin. The Panini Phoenix 'fire' logo is present at the bottom center, though the inconsistencies strongly suggest a production anomaly.
