Chicagoans are also familiar with the redheaded gal that adorns the sign at downtown's Redhead Piano Bar, who may or may not have been actually inspired by a real person.
But a real live person will soon be the face of the popular bar as they embark on a search for a "fun, fabulous redhead" to appear in their new ad in a future issue of Michigan Avenue Magazine.
The search for "The Ultimate Redhead" takes place on Sept. 17 at The Redhead Piano Bar (16 West Ontario St.) between 6 - 8 p.m.
And don't worry if you're not a real redhead -- dyed versions are also welcome.
The competition will be judged by notable locals Lou Canellis, Susanna Negovan, Kelli Zink and the audience.
RSVP to firstname.lastname@example.org by September 15 or click here for more information.
