"Tienture Idéale, aux colorants actives" 

Translation: Ideal hanging, with active dyes

This beautiful vintage poster has a brilliant color scheme -- a light blue background frames a blonde angel, stretching out a rainbow clothe dripping water like delicate raindrops. 

Original artwork/maquette by Raoul Eric Castel. This working drawing of the poster for Tienture Ideale shows creases in the text at the top of the artwork; there is also a color smudge just below the rainbow. This piece has been linen backed.
