I was glad to inherit my Mom's huge and complete set of Cuthbertson Christmas china - including the coffee cups. She kept expanding it, so the designs vary a little as the company made minor changes over the years.
My sibs still get to use and see them here at the Maggie's HQ, every Christmastime. It is sentimental for all of us.
Like most nice stuff, they are not ok for the dishwasher despite what they may say.
Frederick Cuthbertson of Greenwich, CT, designed these classic and charming things in 1922 for his shop in NYC. Still made in England, though. You can buy them today and leave them to your kids. They don't get heavy use.
