1957年，巴西赠送给联合国题为“战争”和“和平”两幅壁画，每幅宽34英尺，高46英尺，由巴西艺术家坎迪多•波尔蒂纳里绘制，位于大会大楼一层代表厅的东、西墙上。

Two huge murals by Brazilian artist CândidoPortinari, entitled Guerra e Paz (War and Peace) can be found at the delegates hall. Portinari intended to execute the work in theUnited States. However, his visa was denied due to his communist convictions. He decided to paint them inRio de Janeiro, and they were latter assembled in the headquarters. After their completion in 1957, Portinari, who was already ill when he started the masterpiece, succumbed to lead poisoning from the pigments his doctors advised him to abandon.
