The 1994 Fleer Ultra X-Men "Super-Villains" Mr. Sinister #56 is a vintage non-sport comic book trading card manufactured by Fleer Corporation that presents a dark, stylized portrait of the manipulative geneticist clenching his fists. Fully painted by acclaimed comic book illustrator Dan Brereton, the artwork vibrantly balances Mr. Sinister's classic purple metallic armor body lines against a bright crimson high-collar cape, framed entirely by his iconic tattered black cape tendrils extending across the backdrop.
