In 1963 Chagall was commissioned by André Malraux to decorate the ceiling of the Paris Opera. He divided the vast space into several colour zones and wove together scenes and characters from the most beloved operas and ballets. The mural would honour the works of fourteen composers, from Mussorgsky to Mozart and Beethoven to Tchaikovsky . Chagall’s ceiling was unveiled on September 23, 1964 during the finale of a Mozart's Jupiter Symphony, the artist’s favourite composer. As the music swelled the great chandelier lit up to reveal the mural.
The opera house also asked Chagall to design a limited edition poster for the ceiling’s debut. The artist based the poster on a portion of the mural featuring Tchaikovsky’s Romeo and Juliet; the famous lovers hover in the air above Paris.
