This from Eric Haak:

The following are rare images of the Mickelberry fire on February 7, 1968. The first image is the only image I know that shows the building before the 3rd explosion which leveled the plant. If you can view this image in a larger format, you can clearly see the people waiting on the roof to be rescued. There is at least one truck parked in front without it’s aerial up and there appears to be a chief or two looking up at the men on the roof. There is also either a truck or engine arriving northbound on Halsted. Image 2 was badly scratched and still has quite a bit of damage. Image 3 shows the helicopter used by Chief Quinn to access the scene. Image 4 shows the gasoline truck in the alley after it had been cleared of rubble. Many of the other images are self-explanatory. The last is damage that occurred to one of the rigs on scene.
