This plaque is made of either copper that has been patinated or perhaps bronze, as it is quite heavy. It has a wooden back over the metal so without removing it I can’t be sure. It depicts a Capercaillie in the forest and the panel is 7 x 5 inches with a wide ebonised oak frame taking the piece to 10 x 8.5 inches in total. I can’t see a signature but it may be under the frame..  It is in very good condition, not sure if there is a bend in the metal or small crack in the corner as shown. More illustrations can be provided and I am happy to combine postage on all my items.
