From the great age of Filedrawer Skyscrapers: the 1914 tower built for the First National Bank and the Soo Line, a railroad.

At the time, buildings in this style were deplored for their bulk, for the way they cast shadows for blocks. The overwhelming size of an almost identical structure in New York - the Equitable Building - led to zoning restrictions that changed the style of skyscrapers in every American city.

Identical in design, not size, incidentally. The Equitable could have eaten this building as a mid-morning snack.
