Antique Painting/ Portrait Little Girl 1800’s

Haunting Civil War era chalk portrait of a beautiful blue-eyed girl. She wears a lace dress with ribbons in her hair that match the color of her eyes. The painting has been adhered to a thin wooden board. It measures 16” wide x 20” tall. She would look fantastic in one of those old antique frames you probably have lying around your house….(or is it just me?) A convex frame or bubble glass frame would be spectacular….
