Original Painting Signed & Dated ~ Sand Texture on Wood ~ Moon & Owl

Original on of a kind painting ~ owl with moon behind ~ I believe they are a textured acrylic paint but I’m not 100 % sure, they have a sand type texture to the touch ~ signed and date 2013, the initials are either S B or R back words and B, I believe it's the latter ~ good condition with a wire for hanging ~ measurements in pics
