I’m sorry, but it seems there is a mistake. The image you’ve provided does not display “The Wave” by Erte or any artwork. It’s an empty frame without any image or artwork in it. To provide a description of “The Wave” by Erte, I would need to rely on existing knowledge because the image you’ve shared cannot be used to describe the artwork.
“The Wave” by Erte is a symbolic painting associated with the Art Deco movement, a genre known for its rich colors, bold geometric shapes, and lavish ornamentation. Erte, the artist, was a well-known figure in the Art Deco scene, celebrated for his glamorous and stylized aesthetic. While I cannot see the specific artwork here, based on Erte’s typical style, one could expect “The Wave” to feature elegant lines, possibly presenting a dynamic and stylized interpretation of a wave, with harmonious forms and perhaps a romantic or evocative atmosphere, characteristic of Erte’s approach to art.
