A claustrophobic collection of plastic tubes, barrels, whatnots and widgets at Mallinckrodt's chemical facility in downtown St. Louis; for an expanded (vintage) tour of St. Louis industry, MoHist has just uploaded a batch o' scans to their Flickr page, including some neat old images snapped in factories and warehouses. --Stefene Russell
