Has anyone come across imitation Lunch at the Ritz jewelry?

The Lunch at the Ritz jewellery that I have seen is signed on the back. I have seen similar earrings but none with inaunthetic signature plates. If you can get the menu card, that is ideal. But also, all of the styles have names so you could ask for the style by name. I'm a fashion journo but not as knowledgeable on this line as with other costume jewellery. Hope that helps Syl from HipGuide
