Still unsatisfied, New York Central proposed in 1961 to build a
three-level bowling alley over Grand Central’s Main Concourse,
which would have required lowering the ceiling from sixty feet to
fifteen and cutting off from view its glorious blue mural of the
zodiac. This, too, was stopped. Foiled again, New York Central
resorted to plastering the terminal with ads and bombarding
travelers with canned Muzak, complete with commercials, over the
public address system.
