The project and its realisation were the responsibility of the Milanese architect Giò Ponti, who intended to add value to the banner using both materials and techniques. The metallic parts of the banner were created by the Ravasco firm, and Alfredo Ravasco, the company director, wanted to donate precious stones. Meanwhile, the Bartelli firm had completed the gold and silver embroidery on pure silk. The banner was inaugurated by Cardinal Ildefonso Schuster on 24 March 1935 (the first day of the Festival of Forgiveness) during a solemn function held in Milan's Duomo.
