This from Jim Skrabel: I just starting scanning old 35mm photos of fires I have been to over the years and came across these. This is the River North Art Gallery Fire at 361 W. Superior St. from April 15, 1989. This fire was a 5-11 and either one or two specials. I heard Aerial Tower 3 box it, grabbed my camera, and headed for the fire. By the time I got downtown (living in Cicero at the time) the fire was already a 4-11.
