Original antique Art Nouveau tile, made in England. The floral decoration was created using the tube-line technique, in which thin clay lines prevent the glaze colors from running into each other.The tile is in very good condition, with a bright and clear glaze. There are minor signs of wear, such as a few small glaze chips along the edges. I have no clue about the maker of this tile — the back does not provide enough information, and I have not found this particular design in any of my reference books on Art Nouveau tiles.
