This from Eric Haak:

Here are six images of the well documented fire at the International Harvester Works at 26th and Rockwell back in the early 1970s. Included is a nice image of Big John working with the county courthouse in the background. I also thought it was an interesting image showing them cooling off the buildings from the radient heat. In the image that shows Engine 18 in front of the building, it is hard to see but a firefighter is holding a small child in his arms and the kid is wearing a firefighters costume. That kid probably still remembers being there even though he looks like he couldn’t been more than 5 at the time. Enjoy!
