Since Barack Obama became our 44th president, his face has actually become slightly less ubiquitous than it once was (he still appears in our dreams on the reg). His likeness remains as inspirational as ever, though, a fact that "Officially Unofficial - Inspired Art for Obama" should reinforce.

The exhibition of prints, posters, photographs and videos inspired by Mr. Change runs April 1-May 31 at the Chicago Tourism Center, 72 E. Randolph. Participating artists include Ray Noland (the "GoTellMama!" poster series), Shepard Fairey (the infamous "Hope" poster) and Sol Sender (official Obama '08 logo).

Admission is free; hours are Monday-Saturday, 10 a.m.-6 p.m. and Sunday, 10 a.m.-5 p.m. There will also be special gallery talks at 12:15 p.m. on April 16 (Noland) and May 28 (Scott Thomas, curator and former Design Director of the Obama campaign).
