lobby and outward onto the sidewalk. The storefront windows in the lobby are more ornate versions of those outside. The lobby originally contained a "palatial" bus terminal operated by the Baltimore and Ohio Railroad. The terminal was outfitted with marble surfaces and also contained waiting rooms and ticket offices. Buses would pull onto a revolving turntable within the terminal, which received boarding passengers on one side and deposited alighting passengers on the other. The coach terminal closed after the railroad discontinued all passenger service north of Baltimore in 1958. Upper floors The third through 48th floors consist almost entirely of leasable office space, while the 49th and 50th floors contain the Chanin brothers' boardroom and offices. When completed, the 50th floor also had a small movie theater (known as the Chanin Auditorium), later converted into the Chanin Organization's offices. Decorated in black and silver, the auditorium had 200 seats across two levels. It also had a stage and projection booth, allowing the venue to be used for films, plays, concerts, and radio shows. In addition, tenants used the auditorium for meetings, and the space also held conferences and conventions. The floors above were originally the offices of the Chanin Organization, with an Art Deco restroom that a building trade convention's judges referred to as "America's finest bathroom". This bathroom was decorated in orange and white, and it contained etched-glass shower panels and brass fixtures. Irwin Chanin's 52nd-story offices were accessed through a set of wrought-iron gates designed by Chambellan. The gates are decorated with symbols of "the spirit of modern industry", such as cog wheels and coins. There were bronze vector grilles within the office. Chanin also decorated his offices with wrought brass and iron; etched glass; and several types of marbles, woods, and leathers. His reception room had complementary furniture and wall paneling, as well as recessed ceiling lamps. The reception room also contains illuminated panels depicting areas in which Chanin was an active developer, such as bridges, skyscrapers, Broadway theaters, and rapid transit. As a dominant landmark in the midtown skyline upon its opening, the building had an open-air observation deck on the 54th floor. It was one of three open-air observatories in the city following World War II, the others being at 30 Rockefeller Plaza and at the Empire State Building, though there had been several other observation decks in the city prior to the war.
