The Belle Epoque and Art Nouveau. In 1891, Toulouse-Lautrec's extraordinary first poster, Moulin Rouge, elevated the status of the poster to fine art and touched off a poster craze. ... Just three years later, Alphonse Mucha, a Czech working in Paris, created the first masterpiece of Art Nouveau poster design & much much more. Fantasy Nouveau posters became just as sensational during that time. Here's 4 fantasy posters that I just love by Nouveau scrapped with a fantasy feel. Scrapping for fun!
