The 808 Building.
The 808 was the sort of structure no one notices until there's nothing like it around anymore. A WW1 era in the Star-Trib archives shows that it began life as a four-story structure, with four more floors added later. You could still see the ragged brickwork above the fourth floor, indicating where the old cornice had been.
In the late 20s they remodeled the lobby, filling it with with Art Deco motifs. Real Art Deco, not the Moderne stuff people often confuse with true Deco.) Polished brass elevator doors; terra-cotta faces. An elegant interval between the street and the offices above.
