You might want to check with the Olympic Museum which opened in 1993
in Lausanne, Switzerland.  An article in the Washington Post in June
that year said:  "Devoted to the Games' history and meaning, the
museum boasts artifacts...paintings and sculpture, extensive film,
video and photo archives."   The article refered the interested to
the Swiss National Tourist Office and gave this number: 212-757-5944.

While we are at it, I cut out and saved that article (now yellow and
crinkly) because I was interested in looking at the evolution of
Olympic Opening and Closing Ceremonies within a (performance) art
historical perspective--with particular emphasis on such recent
phenonenon as the use of Trinidadian Carnival traditions to
illustrate Basque history for an international television audience.
I've had the idea on the back burner for years but hopefully it is
not as yellow and crinkly as the article. Does the idea spark any
associations out there about work currently being done in connection
with the historical analysis of performance art/public spectacle/
public art?  I'd be interested in any referals.  Or any
recommendations about how to state my interest more succinctly....
