Silver Spoon-marked "RITZ PARIS" w/crest NR

we have a "Souvenir" spoon that probably "freed" from custody of the "Ritz Paris" at some time in the past. The spoon is fiddleback design, with a shell pattern on the top, on the back the spoon is marked "RITZ PARIS" and a nice Crest topped with a Crown below the Shell pattern on the fiddleback..Don't know the maker, but in research I found that "Christofle" was a maker for Top Hotels and Restaurants, they worked in both Sterling & Silverplate. Any questions please ask. No Reserve.. Happy Bidding
