Spine Stretching Cast

This drawing is new and based on a photo I saw in an old medical textbook of a cast used to help straighten the spines of scoliosis patients. It seemed so strange and archaic that I wanted to draw it. You might have to click to look at the larger view to get all the detail. Trying to decide whether I want to color it. I kind of like it black-and-white since that's the way the old photo was.
