Miniature hand painted with the portrait of a man wearing a wig and a lace collar, definitely an aristocrat or noble, in a blackened wooden frame with a seal with the coat of arms composed of a double crest crowned XIXth century.
This miniature is in good condition, it still has the seal back.
A note: the miniature moves slightly in its frame, scratches and wear on the frame slot on the thumbnail (on the left side garment), see photos.
