The solid cast bronze tiles are signed and dated by artist Norm Lewellen, and made in the USA. Each image is available in the two patinas shown above, verdigris and antique brown. The tiles have a live finish, and will continue to develop their own unique character with age. If you wish the appearance to remain unchanged, we recommend applying Butchers paste wax or a light oil such as watchmakers oil, test on the back of tile for desired results.
