Compare the Air! Photo #1: Men standing in the smoky air in front of the St. Louis Main Library downtown in January 1940. Coal smoke made St. Louis a dirty place before a new ordinance that year began making the air cleaner. Photo #2:Men pose in the same location one year later, in January 1941, another effort to show the contrast in haze since the Board of Aldermen enacted the citys hard-coal ordinance in April 1940. Post Dispatch.
