Illinois Central Gulf Railroad's City Of New Orleans pulls out of Chicago in 1971...the RR Donnelly Press building is in the background, where they used to print phone books. It is now a massive data center. This photograph would be impossible to recreate as those rails are completely covered at this point by the Mccormick Place North Building. Also note that the tallest buildings in the background are the Chicago Board of Trade and The First National Bank Of Chicago, both now buried among taller structures.
