Cabinet card, 6 ½ x 4 ¼. View of woman balancing on large ball. There is a later pencil id on back”Nelle Lansberty”( though a quick internet search did not result in any information).  No photographer’s imprint . Apparently mounted at some point, the back has been skinned and exhibits some roughness, the image has very good tonality and contrast, tip of mount corners clipped. Cc cs 112
