Authentic Fragonard French Porcelain 8 0z. tumbler with lovely matching coaster

This unique tumbler has been described as a Guest Room water glass with coaster. Some said it was a toothbrush holder and soap dish? Some a trinket dish and pen holder. It is lovely and marked on bottom Fragonard Parfumeur (registered model created and developed by Fragonard) translated. A little over 4" Tall & Coaster is 4.5" round. Thanks for Reading.
