Oregon photographer, little girl daughter of civil war major dated & ID'd photo

  
Original tintype of a little girl identified on the back as Anna Mary Rinehart, and dated 1872. Looks like a photographer's light reflecting screen partially visible on the right; the tintype isn't very much bigger than the oval viewing window so that there is not much more hidden under the mat. Anna was born in 1870 in Canyon City, Oregon and was the daughter of Civil War Major and Oregon pioneer William Vance Rinehart. Very good or excellent antique condition with a couple of light bends. Dimensions are 3.5" x 3.5".
