This may well be the first instance of a Persian king appearing in a foreign advert. See full image. (Not to be outdone, Mozaffar-din Shah would appear in a typewriter ad.)
Rare pictures of Nasser-din Shah’s 1899 visit to London can be found at Google’s LIFE magazine archives. Iranian.com has its own archive of Qajar pictory thanks to the tireless work of Darius Kadivar & Jahanshah Javid.
