File:Captain Cook's antimonial cup.jpg

Summary
Fair use rationale: This historic photo, which cannot be re-created, is not being used for profit but rather, only being used for informational and educational purposes in terms of a public policy matter substantially within the public interest of the people interested in ancient medical devices and relics associated with Captain James Cook. Its inclusion in the article adds significantly to the substance of the article because the photo depicts what an "antimonial cup", "pocula emetica," "calices vomitorii," or "emetic cup" is.
