Vivid Oil Pastel drawing and gold metallic leaf. Each of these originals are on my nifty 6X6 wood panels. They are ready to hang or sit, with no glass needed. The cradle of the panel is 1 5/8 inches deep, poplar wood. The oil pastel is protected by multiple layers of resin so that the surface can be wiped with a damp cloth, if needed. My painted panels are very sturdy, and the surface is composed of dense Masonite coated with a black gesso. These originals also have a top coat of glossy Liquitex acrylic varnish.
