What Sin City is
Frank Miller introduced Sin City in Dark Horse Presents Fifth Anniversary Special (April 1991). The noir-crime urban setting (Basin City in canonical text) became the location for Miller’s Sin City graphic novel series across multiple books through the 1990s and 2000s. The 2005 Robert Rodriguez and Frank Miller film extensively adapted the universe with stark black-and-white visual effects preserving Miller’s panel composition; a 2014 sequel followed.
Collector context
Dark Horse Presents Fifth Anniversary Special trades modestly. CGC 9.8 is in the low three figures. The book is recognized as the foundational Sin City reference and as a Frank Miller-era key.
