County of Allegheny (1989):  This case dealt with whether or
not the state putting up holiday displays on public property was a
violation of the Establishment Clause of the First Am.  Scalia
sarcastically referred to Allegheny as the case where the U.S.
Supreme Ct. decided to become “interior decorators.”  Two holiday
displays were put up in downtown Pittsburgh.  The first display was a
creche (a representation of a Nativity scene) placed on the Grand
Staircase of the County Courthouse.  The second was a menorah placed
just outside the City-County Building, next to a Christmas tree and a
sign saluting liberty.  Were these displays a violation of the
Establishment Clause of the First Am.?
