This is an oil painting on an 9x12 canvas board.
Based off of Bob Ross's "Splendor of Autumn" from season 28, episode 10 of The Joy of Painting.
There are multiple versions of this painting available in my shop. Each one has it's own listing and is still unique because no two paintings are ever the same. Whenever I teach a class I end up with multiple versions of the same painting. This painting is the one I did prior to the class to have as an example.
You can view each listing to compare and choose your favorite. In the photo of the two paintings together this painting is the smaller one on the left.
