No artist mark but I believe this to be a photo taken by Jacqueline Seaver in conjunction with Rick Warner who worked for Kodak – these show are not only the test prints used in the Vitallium promotional materials, but also the documentation of the shoot setup (likely also used in publications to teach photographers but I found no tear-sheets from such). Dating is unknown, likely 1958 based on dating of footnotes. Use these to frame in your office or to keep as historic artifacts from medical or photography perspective. You are getting all prints as-seen – exceptional example of how the same item can be depicted so many ways.
