My brother has been back out East for the last decade and for a couple of birthdays he has sent me tiles from the Moravian Pottery and Tile Works. Their home page is on the Bucks County website. The two I now have are handmade tiles that he felt I would particularly like, and I do.
One is of a jousting knight and the other of a dragon.
The backs bear the makers marks from 2007 and 2009. I hope to visit the works someday and also check out the Mercer Museum which includes many "working" exhibits on crafting.
