An outstanding miniature silhouette portrait

A stunning English 18th century, signed antique miniature signed silhouette portrait of a woman, with an oval glass front, made mid 19th century, I’m always in awe of how these beautiful and detailed pictures are done, these pictures are framed and presented in a oval trim, the antique condition is good, to the top of the frame is a little metal moulded finial without hanging loop though , a great antique ready to go
The picture measures 5.2” x 6”
