Opera 

"Opera" is an illustration by the Art Deco artist Erte, who was known for his glamorous and stylized designs. The artwork depicts two women in elegant attire at the opera, one adorned in a black gown with ornate embellishments and the other in a vibrant red gown. The theatrical setting is emphasized by the ornate interior, the use of decorative details, and the figures' poised expressions. Erte's work often celebrated the luxurious and glamorous lifestyle of the 1920s and 1930s, and "Opera" is a prime example of his signature style.
