Actually this is a comment on trdking's response..... I did not know that pottery was often purchased plain then decorated locally. Was this a 19th century thing? 20th century? It would explain some old shards I have dug up.... a lot of plain stoneware pieces but some with designs I cannot identify. What's more, some of the plain shards have remains of pencil marks in the shape of leaves! Were there that many local craftsmen who could decorate ceramics like this?
