Acrylic, collage, on thin, gessoed, birch panel 7.5 x 11.75 inches, signed lightly in pencil. No framing on this piece is necessary! The panel painting is attached with 100% silicone adhesive (removable), to a recessed wooden back support, 1 inch deep. The back support is notched at the top to hang perfectly flat on your wall from a screw or nail....no other hanging apparatus is needed. This method of presentation pushes the piece visually forward, without the visual distraction inherent in most frames. Should you wish to present this piece in another way in the future, the painting can be removed with no damage to the panel.
