The steel sun background is buffed to create a swirling effect that changes as you move in front of the piece. The steel moon is heat-treated to 6000 degree bursts creating a unique blue/brown effect and is raised .75" off the background. The copper stars are raised 1" off the background. This has a beautiful, multi-layered other-worldly look that will compliment any surrounding. You'll hang it from either the top or bottom flame. Available in 3 sizes: 11", 17" and 26". Custom sizes available - just ask!
