The Big Football, originally uploaded by raywert.

The colors made me think it was a Steelers football, but it turns out it’s promoting the official vehicle of Super Bowl XL (click for photos of the nifty banner Cadillac has).

The photographer, Ray Wert, is better known as the blogger DetroitWonk. On his site, he has great stuff about Detroit every day including highlights of discussion elsewhere in the Motown Blogverse.

He also tipped us of to the very cool webcam for Campus Martius Park (site of the Motown Winter Blast).
