Turkish Copper & Zinc Wall Plate 1980s

Vintage copper and zinc(assuming) engraved wall decor plate hand-made in Turkey. Swirl and floral pattern with petal like shapes along the rim. Measures about 7" wide. Some light tarnish shown in photos but no noticed major damage like holes, cracks, etc. For whatever reason, the zinc engraved areas are catching light weird and look more green--they actually have a bright silver/chrome shine. Colors include the copper, zinc, and dark brown surfacd in the smooth areas.
