IDS Center was completed in 1972, and for now is the tallest building in Minnesota at a height of 792 feet depending on how one measures it.  IDS was constructed as the headquarters of Investors Diversified Services, Inc.—now Ameriprise Financial — and consists of five parts: the 57-story IDS Tower itself; an 8-story annex building; the 19-story Marquette Hotel; and a 2-story retail building originally dominated by Woolworth’s. These four buildings are joined by the 7-story Crystal Court as you see in the postcard.  The unused card’s caption explains even more.  Grade: 1
