Clara Barton, head-and-shoulders portrait, facing front

Library of Congress catalog record for a 1904 studio portrait photograph of Clara Barton, copyrighted by photographer J. E. Purdy of Boston, held at loc.gov/pictures/item/2005693027/. The Library of Congress site currently returns an automated-access (Cloudflare) block to this archive's fetch tooling, so this bundle uses the image's Wikimedia Commons file page (commons.wikimedia.org/wiki/File:Clara_Barton,_head-and-shoulders_portrait,_facing_front_LCCN2005693027.jpg) -- one of this archive's four supported, machine-verifiable archives -- as the resolvable holding record instead. Commons carries the file, sourced from LOC's own digital copy (LCCN 2005693027), under a Public Domain Mark, stating the work is in the public domain in the United States because it was published before 1 January 1931.
