This from Eric Haak:
This week I am sharing these images from a 5-11 alarm on January 28, 1965. This was an abandoned grain mill at 2203-09 South Lumber Street. For those who are familiar with this area, it is the present location of Ozinga concrete just south of Cermak along the Chicago River. The second image is of Engine 8 and the last image shows Engine 23. I can count 13 master streams flowing in image 4. Still time was reported as 4:47pm. Hope you enjoy.
