Lincoln Park: You Know What You Should Do

Artist Jeff Zimmermann incoporated portraits of real people who use Oak Street Beach in his lively mural, 2012, photo by James Iska.

The mural includes an iconic depiction of Uncle Sam pointing out in a manner that makes the viewer think he is serious about keeping Chicago's beaches clean, 2012, photo by James Iska.

The artwork includes familiar American icons such as a Chicago hot dog and an ice cream cone. But there are surprises. For instance, a rendering of an ordinary African American man is presented in place of George Washington's face on the dollar, 2012, photo by James Iska.

You Know What You Should Do provides a visual message about what not to do, such as feeding birds on the lakefront, 2012, photo by James Iska.
