Many people don’t know that The Calling by Mark di Suvero (the orange sunburst sculpture that sits at the lake end of Wisconsin Avenue) has been part of the Milwaukee Art Museum’s permanent collection since the sculpture’s creation in 1981.
The Calling has attracted a lot of attention and inspired quite a bit of dialogue by Milwaukeeans over the years, including here in an 2006 article that answers the question “Will they Move the Orange Sculpture”.
I’ve found that people either love it or they hate it, as summarized in this 2007 Milwaukee Journal-Sentinel article.
Recently the United States government indicated on which side of that line they stand: they awarded artist Mark di Suvero the National Medal for the Arts. You can read more about the awards at the National Endowment for the Arts website.
