This is a vintage black and white photograph depicting a person performing a shoulder straightening exercise with a towel. The person is standing with their arms extended horizontally, holding the ends of a long towel that is looped around their body, forming a large, blurred circle. The person is wearing what appears to be a short-sleeved shirt and shorts, and their feet are clad in simple shoes. The image has a slightly blurred, ethereal quality, likely due to the long exposure time used to capture the movement of the towel. The background is completely black, emphasizing the figure and the circular shape of the towel. Below the image, there is text that reads 'FIG. 18—SHOULDER STRAIGHTENING WITH TOWEL.' and page numbers '9' and '129'.
