Can You Name This Twin Cities Location?

The corner building in the photograph's foreground was the headquarters for one of the largest and most successful organizing drives among itinerant workers in North America.  The Minneapolis locals of the IWW moved into the building in late December of 1913 and had published this description of the hall in an April 1914 issue of Solidarity:

Though the structure has since been torn down (a discouraging and all too common trend in the Mill City), there are several details in the photograph that betray its original location.  Note that the two buildings to the right of the corner building still stand and very much look like they did when the photograph above was taken.  Another hint - the main entrance to the corner hall was not the light-colored brick storefront with large windows, but was in fact around the corner on the long side of the building - where you see the small wooden entryway.

Can you name the location where this important chapter of North American labor history was written?  Maybe a prize is in order for the first person who correctly identifies the intersection or address?
