Here is an excellent acrylic example from Clayton Singleton: “…painted with layers of color covered with one “skin” color overlayed with an image of Obama with the Presidential oath written and scored throughout the image. I painted this after Barack Obama won the 44th Presidency. It was displayed in The Selden Gallery and published on January 20, 2009 in Portfolio Magazine.”
Measures 3′ x 5′. Zooom to see the detail.
