Cote d' Azur, Le soleil toute l'anee, Roger Broders In his job promoting the Paris-Lyons-Mediterranean Railway, graphic artist Roger Broders (1883 – 1953), was pivotal to poster art’s initial wave in popularity. Defining vintage travel poster art of the 1920’s and early 1930’s, his distinctive, exuberant Art Deco style goes along with his ability to evoke the romance and nostalgia of travel. A taste for luxury travel, exotic locations and leisure activities was a feature of the hedonistic post-war years of the 1920s. Sports and outdoor activities were all the rage, and people were travelling more for pleasure than ever before. #14. Australia, The Tallest Trees in the British Empire, Percy Trompf (~1935) #13. In a German Forest (Deer), Jupp Wiertz (1935) Matter's eight revolutionary travel posters for the Swiss Tourist office were the first to use photography as collage - purely as a design element such as type. Matter in the years after 1932 produced what are widely regarded as some of the most celebrated posters in the history of design. Commissioned by the Swiss National Tourist Office, his groundbreaking works such as 'All Roads Lead to Switzerland’  and 'Pontresina’ further developed his new found awareness of the formal elements of photography. No longer manufactured as discrete isolated images, he now composed the photograph in such a way that it came to function as a single element in the totality of a graphic design.
