My favorite bit of Edison Paris-related material -- an autographed place card from the luncheon presented in Edison's honor in the restaurant Brébant in the Eiffel Tower by the Société des Ingénieurs Civils on Sept. 10, 1889. After the lunch Eiffel invited the guests to a reception in his apartment at the top of the tower, at which time Edison presented the Class M to Eiffel. As they were leaving the restaurant Eiffel noticed composer Charles Gounod finishing his lunch and graciously invited him along, even though Gounod had been one of the fiercest critics of the tower when it was first proposed.
One of the guests at the party prevailed upon Edison, Eiffel, and Gounod to all sign the back of his place card as a souvenir. The party went on all afternoon, with Gounod entertaining on the piano and (no doubt) the phonograph showing its wonders. The story of the luncheon and party is well-described in the book "Eiffel's Tower" by Jill Jonnes -- a delightful book that I can highly recommend to anyone interested in the history of the machine age.
