Awesome vintage ‘70s glazed ceramic tile scene of ocean & 3 butterflies

11x 14” glazed tile. Water scene of ocean and 3 butterflies. 2 with winged jewels. Colors are separated by a line of metal. Looks like copper but I’m not sure. Back is covered with dark blue felt and a hook to hang. Some of the white clouds show crackling but I understand this is normal with age. It is hard to see. I had to look at an angle to see it. Was able to capture it in the photo of clouds. Weighs 3.7 lbs
