Inspired by the urban street photography featured in "Street Seen: The Psychological Gesture in American Photography 1940-1959" at the Milwaukee Art Museum, I will share a snapshot of a Milwaukee landmark each day for the 10 days leading up to "MAM After Dark"on March 12.

Yesterday's photo: The Grain Exchange or The Mitchell Building

Built in 1879, the Grain Exchange building, 225 E. Michigan St., is best known today for its large ballroom that serves as a wedding venue.

But at one time, it served as the hub of Wisconsin's grain market. Between 1950 and 1970, wheat was the area's chief product and it was in this building, that trading and inspecting took place.
