{1} This information was given to Mr. Cain in a letter dated 5 August 1947 by the dealer Arturo Grassi and has not been verified, see IMA Historical File (51.98). No Counts Orsini-Baroni have been identified; Luca Orsini Baroni [1871-1948] was the Italian ambassador to Germany in the 1920s but it is not known if he has any relation.
{2} The art dealer, Luigi Grassi [1858-1940] and his brother Giulio are identified on the Art Looting Investigation Unit List of "Red-Flag" names, see Nancy Yeide et al., The AAM Guide to Provenance Research, 2001, p. 289. Arturo Grassi was Luigi's son. He and his sons, Marco and Luigi, continued the family business in Florence and Brooklyn, and were accused of illegally exporting Italian art in 1969, see New York Times, 25 May 1969.
