In one position she is resting her gloved hands alongside her face and she wears a necklace with small pendant. When turned over and her head is covered the scene changes to her feet with stockings, bare legs, and small dark mark at center representing her pubic area. Tiny surface dents with small tan mark on extreme right edge which is in the development of the photographic paper. Still with full gloss. VF and displays NM. Only example we've seen.
