Old Chicago Photos - ChicagoPhotoShop
This photograph was probably taken in 1925, since the vantage point seems to be the Tribune Tower (1925). The London Guarantee and Accident Building (1923; now 360 North Michigan Avenue), and both the Wrigley Building (1921) and its Annex (1924) are completed, while Wacker Drive, which opened in 1926, is under construction. Grant Park is still largely undeveloped. Illinois Central facilities dominate the area south of the river and east of the buildings that line the east side of a widened Michigan Avenue.
