Mohammad Reza Shah Pahlavi, King of Persia (Iran) welcomes King Faisal of Saudi Arabia in Tehran, 1974.
This rare photo was originally published in the state Persian-language periodical 'FARMAN'. The title of the volume is 'Tarikh-e Talayi-e Asr-e Pahlavi' [The Golden Age of Pahlavi Era].
King Faisal ruled Saudi Arabia from 1964 to 1975 and Mohammad-Reza Shah Pahlavi was the king of Persia from 1941 to 1979.
Since the 1979 Islamic Revolution in Persia, the countries are in cold war with each other. In 1987 during the Hajj ceremony, hundreds of Iranians were killed in a clash with Saudi security forces and in 2006 the Saudi Embassy's building in Tehran was set on fire with Molotov cocktails.
