Chicago-area families are invited to Wrigley Square in Millennium Park (Michigan and Randolph) from 11 a.m. to 2 p.m. Saturday to have a free photo snapped by famed Paris-based photographer Uwe Ommer, reports the Sun-Times. One lucky family’s photo will be in Family Album, the photog’s 102 oversize photos of families from around the world, in Millennium Park this Friday through Sept. 26.

Since it didn’t say what kind of families, one could assume they are open-minded.
