The “Copper King” (Feb, 1939)

The “Copper King”

EMBODYING the latest scientific streamline design, with interior decorations of sparkling copper and featuring Polaroid windows, which provide the basis for the claim that it is the world’s first light-conditioned observation lounge car, the “Copper King” has been placed in service by the Union Pacific Railroad as an addition to the railroad’s famous diesel-electric streamliner “City of Los Angeles.”

Each of the 29 windows of the “Copper King” consists of two 27-inch Polaroid discs, mounted one over the other in such a way that the inside disc can be revolved by turning a knob, enabling the passenger to regulate the amount of light passing through the discs.
