A correction from the June 1983 issue of Doorknob Collector:
“In the last issue we incorrectly identified the knob at left as coming from the LaSalle Hotel. The knob is actually from the Lexington Hotel, Chicago. Al Capone at one time used two floors of the Lexington as his headquarters. The name was changed to The New Michigan Hotel after Capone’s demise. The knob pictured below is the correct LaSalle knob.”
