Ladies on a Beach by Georges de Feure (1900)
This reminds me a lot of the work by Yoshitaka Amano... who did the character designs for the Final Fantasy video games, I believe, as well as... was it called The Sandman? -- written by Neil Gaiman?
These women look like they just came waltzing out of the sea, onto the beach... It's so magical, like some kind of strange dream...
