A little history about Ridgway & Pomerania -
This platter is made in what's called the transfer printing process. And this is a process that was developed in the 18th century. It involves having engravings that are then put onto a paper that is then put onto the porcelain. This particular kind of platter was made in Staffordshire, in England. There is a mark on the back of it that helps us identify. That little cartouche there with the word Pomerania in the middle. Pomerania is the name of the pattern. And Pomerania was on the Baltic Sea between where Germany and Poland are now. This platter, identifiable by the cartouche, because there is a particular Staffordshire factory that used that kind of cartouche. It's identifiable as having been made by John Ridgway. John Ridgway, as a Staffordshire manufacturer, specialized in this kind of ware.
