With the Ohio River on one side and railroad tracks atop a raised embankment on the other, the Jones & Laughlin steel mill had few entrances. During the mid-1930s these were protected by armed guards with orders to keep out potential union organizers. The state historical marker commemorating the Supreme Court's NLRB v. Jones and Laughlin ruling is in front of the green shack to the left of this mill entrance, where Governor George Earle in 1936 ordered the J&L guards to disarm.
