Found above the portal to the Queen Tunnel at the Copper Queen Mine in Bisbee, this plaque greets today's tour participants as they enter the mine by train, just as it welcomed miners a century ago. The 1915 date refers to when this particular tunnel was driven, but the mine operated from around 1880 until the mid-1970s. No other royal has reigned longer.
