Vintage Antique 9 1/4" Round Etched Engraved Brass Flue Cover Romantic Victorian

Description

Unique vintage (antique?) 9 1/4" round brass metal flue cover, engraved/etched with a romantic Victorian scene with fine detail- depicts a young woman laying on the lap of her beloved, with her hand touching his face while he gazes down at her. Flowers, bees, birds, clouds surround them, and the image is bordered with a lovely floral scroll design. The metal lays flat and is about 1/8" thick with a thin layer of old insulation is attached to the back side.
The piece shows age and patina, with darkening, some white substance in the details of the engraving (maybe zinc oxide or old cleaning product?), a tiny speck of white (maybe paint) and a small ding close to the edge. I have not attempted to clean this piece as some prefer an authentic patina. There is hardware attached to it for hanging, so I'm not entirely sure how it was installed, but the insulation indicates to me that this was likely used to cover a flue.
Thank you for looking!
