slideshow: Detroit graffiti artist "Shades" unveils mural at Grizzly Peak

See more photos from the unveiling here Northern United Brewing Company — which produces and bottles beer in collaboration with Grizzly Peak Brewing Company and Jolly Pumpkin Artisan Ales in Ann Arbor and North Peak Brewing Company in Traverse City — commissioned the mural, done by graffiti artist Antonio “Shades” Agee.

Although parts of the work were visible during its creation, the unveiling of the full work — on a 200-foot-wide brick wall — took place in a special event Thursday, called Reveal, as a benefit for the Ann Arbor Art Center.
