Seven U.S. citizens have returned a number of Saudi artifacts which they possessed for decades. The seven U.S. citizens linked these pieces with their memories in the Kingdom of Saudi Arabia in which they were born and lived for many years. Prince Sultan bin Salman bin Abdulaziz, President of the Saudi Commission for Tourism and Antiquities, honored these U.S. citizens during the opening ceremony of the Saudi Arabia Masterpieces Exhibition which was opened at the Smithsonian Museum on November 15, 2012, and will run for three months.
