The design features two clasped hands framed by laurel branches, a powerful symbol of international friendship. The inscriptions appear in Arabic, French, and English, underscoring the global theme. Printed by Thomas De La Rue & Co. Ltd., the set was released in four denominations (1p yellow, 2p red, 3p blue, 4p green). Highly regarded by collectors of UN-related and Middle Eastern philately, these stamps highlight Saudi Arabia’s participation in worldwide humanitarian and peace efforts during the 1960s.
