The building at 3333 W Arthington was the Administration Building for Sears Roebuck before they moved to the tower downtown. You can see the lettering in stone over the triple door entrance. Look it at on Google street view.
Thank you for the insight of the history of the building.
Sears had a brand years ago called "Homart". It eas named after the intersection of Homart & Arthington.
Correction "Homan & Arthington".
