I had a girl who painted do this pan back in 2003 to 2005 when I had an antique/junque store.  So this pan is vintage now.  I sold the business back in 2005 and all my inventory has been sitting in my basement storage area all these years.  Downsizing I decided to bring out those treasures I have in storage.  
This pan is a Taiwan cast iron 6 1/8 inches in diameter x 7/8 inches thick.  She painted a farm scene on it...has the barn and a shed, a few trees, and a path leading to the barn.  We put dry palm tree grass on the bottom and fixed a single birds egg on the grass to make it look more 3D like.  This piece is very unique and she did a good job on the painting of the farm scene.
