Dr. J.R. Brinkley (Bain News Service portrait)

Studio press portrait of John R. Brinkley from the Bain News Service, held in the Library of Congress (George Grantham Bain Collection, LCCN 2014711648) and reproduced on Wikimedia Commons as public domain. Used as the actor portrait for the practitioner. Identification basis: the Commons and Library of Congress record titles the image 'Dr. J.R. Brinkley' and the print itself carries the caption 'DR. J.R. BRINKLEY'. The Bain Collection catalog gives an indeterminate early date; the negative is inscribed circa 1920 and the period is consistent with Brinkley's prominence after 1917.
