'Sentinels' is painted in acrylics on an 11"x14" gallery wrapped canvas. Sides have been painted so framing is optional. Painting has been glazed with a high gloss medium for permanent protection. Photos taken before glazing to eliminate reflective glare from camera flash. 'Sentinels' is an outsider modern abstract piece in my 'Barren Trees' series. Thanks for looking! Patrick E.
