For those who are interested about the Landmarking and history of Johnson Publishing: Here is the report:
https://www.cityofchicago.org/conten...ng_Co_Bldg.pdf
Much like the Essex Inn that was landmarked last year, Johnson publishing is one of three modernist buildings along the Michigan Boulevard street wall that were made eligible for landmarking (the only other that has not been proposed yet is 200 S Michigan, the former BorgWarner Tower).
If you skip to the end of the report, Johnson Publishing was considered to meet four of the seven criteria for designation (only 3 are required). Meanwhile Essex was considered to meet three.
