Hope this helps!|||Yves St Laurent is a fashion designer. His early scetches got him a job at Christian Dior. He known more for his fashion than artwork per-se. You might be able to find a fashionista interested in buying the scetches.|||No you're not the only one. Anyone who owns a YSL haute couture gown owns an artwork by Yves Saint Laurent.
