As to other souvenirs -

The Summer 1997 issue of _Bene Legere_ (Univ. of California,
Berkeley newsletter) had a feature on a possible marble head from
the Parthenon at Athens that was given to MTP by Doris and
Samuel Webster in the mid 1960s.  At the time the article was
written, tests for authenticity were being conducted.  I'm not
sure if those test results were ever published.
