The word "Yes!" will be installed this fall in tall red letters on the curved glass wall to the north of the Main Boulder Public Library's entrance, the city announced Tuesday.

"The iconic image of Yes! will be a must-see for visitors to Boulder, and a legacy to our growing collection of public art," City Manager Jane Brautigam said in a statement.

The project is slated to consist of four free-standing aluminum characters, with light visible through the red surfaces on the three letters and exclamation point.

Yes! artists Rosario Marquardt and Roberto Behar, based in Miami, were also behind the "All Together Now" sculpture at 14th and Curtis streets in downtown Denver. For this project, the pair beat out three other semifinalists and 366 total applicants.

"Yes! consists of one unique and iconic element," Marquardt and Behar wrote in their proposal, "that metaphorically embodies the affirmative essence of Boulder as a distinct American community and the positive nature of the library's mission to enhance free access to ideas for all."

Felicia Furman, a member of the Boulder Arts Commission and the public art selection panel for the library project, called the work, "exhilarating" and "big and bold."

"Whatever your taste in art, this sculpture will make you smile," she said in a statement. "The artists have captured Boulder's vision of itself-positive, confident, sophisticated and innovative. Yes! will be recognized nationally but will still shout out 'Boulder.'"

The installation is part of a larger renovation of the library, which is expected to finish by December and will include a remodel of the children's and teen spaces, plus enhancement of the fiction, music and movies section.
