WASHINGTON--Chicago blues legend Buddy Guy, honored Sunday night as a 2012 Kennedy Center honoree, is the subject of a full page ad in the Sunday Washington Post, paid for by the City of Chicago.

Before the show at the Kennedy Center tonight, President Barack Obama and First Lady Michelle are hosting the seven 2012 honorees at the White House for a reception--full of show biz celebrities.

"From America's blues capital to America's Capitol, Mayor Rahm Emanuel and the City of Chicago congratulates Buddy Guy," the headline reads.

The ad copy continues, beneath a big picture of Guy by Chicago photographer Paul Natkin, "We are proud that the Kennedy Center and President Barack Obama will pay tribute to Chicago's very own blues pioneer and hometown legend, Buddy Guy."

The ad touts the upcoming 30th annual Chicago Blues Fest, June 6-9 next year and plugs Chicago for blues fans tourists with this: "Visit Chicago - The Blues Capital of the World!"

The ad is sponsored by the City of Chicago and the Chicago Department of Cultural Affairs and Special Events.
