At the Riyadh International Book Fair, which ends Oct. 8, auction house Sotheby’s is showing a photo album of the late Queen Elizabeth II’s visit to Saudi Arabia in 1979. Here are three gems from that visit: 1. Here, she and her husband Prince Philip are welcomed by Prince Abdulmohsen bin Jiluwi (L), governor of the Eastern Province and Prince Majid bin Abdulaziz (R), governor of Makkah. 2. Queen Elizabeth II in Riyadh, walking with King Salman (to the right of the queen) and Prince Majid bin Abdulaziz (far right). To the left of the queen, her husband Prince Philip, the Duke of Edinburgh, walks with Prince Sattam bin Abdulaziz, then deputy governor of Riyadh (far left). 3. In this unique image, Queen Elizabeth II stands with three kings of Saudi Arabia: (from left) King Fahd (1982-2005), who was Crown Prince at the time of her visit; King Khalid (1975-1982), who was the ruler at the time the queen visited; and King Abdullah, who ruled from 2005 to 2015.
