"This lovingly compiled site excels at a much-ignored niche: original editions from the Maitres de L'Affiche series - small versions of popular posters specially printed for collectors between 1896 and 1900. Any poster collector will be impressed with the roster of artists represented here: Henri de Toulouse-Lautrec, Leonetto Cappiello, Alphonse Mucha and other graphic masters. And an illuminating mini history accompanies every item. The site's host, a well-respected art dealer, now sells exclusively online and at Vintage Poster Fairs. Best: Thoughtfully written History of the Poster. Worst: Collection sticks mainly to master artists."
Update: I have since expanded my artist listings to include non-masters and full size posters - Greg
