Hand Painted Watercolor Horse. No two pieces are alike. Using a proprietary technique developed over the years, we are able to achieve a Watercolor like effect with these unique pieces. The background is left unglazed to let the matte Terra Cotta show through. All tiles come cork backed so they will not scratch your tables. A hole has been provided at the top of the backing for easy hanging. Each tile is hand glazed, no two are alike and glaze variations are to be expected.
