The front page has a three column heading: "100 Men Trapped in Mine; 300 At Work in Ohio Shaft; Fire and Gas Halt Rescue" with subhead. (see images) Nice for display.
Complete with 16 pages, light toning & a little wear at the margins, some binding slits along the spine, generally nice.

Background: The Millfield Mine Disaster of November 5, 1930, stands as the deadliest industrial accident in Ohio history, claiming 82 lives inside Sunday Creek Coal Company’s Poston Mine No. 6 when a slate fall severed a electrical trolley wire, sparking a violent methane and coal dust explosion. What rendered the tragedy uniquely catastrophic and historically prominent was the presence of top corporate leadership and visiting engineers on an underground tour showcasing newly installed safety equipment—resulting in the sudden deaths of company president W.E. Tytus and key mining executives alongside dozens of miners, most of whom succumbed to carbon monoxide poisoning ("afterdamp") rather than the initial blast. Beyond the tragic irony of the executive deaths and the harrowing survival of 19 miners who barricaded themselves behind a makeshift burlap-and-mud seal three miles deep, the event's lasting historical significance lay in its immediate legislative impact: the widespread public outrage and loss of industrial leadership directly galvanized the passage of major, modernized state mine safety reforms by the Ohio General Assembly in 1931, establishing stricter electrical insulation and ventilation mandates across the region.
