Advertising collectibles include antique posters such as those of Toulouse Lautrec for Le Moulin Rouge, or the Art Nouveau posters of Alphonse Mucha and especially the Art Deco posters by Capiello who is said to be the father of the modern advertising poster. The porcelain advertising sign developped in the 1880s alongside the enamel metal sign. These signs had the advantage of being weather-resistant.
Advertisers used means not only to be seen but also to be used, so as to impose the advertising message. From the early 20th C advertising objects appeared such as thermometers, calenders, mirrors, ashtrays, etc. - all great collectibles!
