From WienTourismus / Vienna Tourist Board:
The annually published Vienna-Journal, which will also appear as an iPad application for the first time in 2012, presents the entire diversity of the city: read interesting and entertaining articles on attractions, art and culture, modern and classical music, the Viennese coffee house, restaurants and bars, as well as parks and gardens in Vienna. To mark Klimt Year 2012, attention also focuses on the painting genius Gustav Klimt, who would have celebrated his 150th birthday this year, and on the modern era in Vienna around 1900. Additional image galleries and videos on the topics give you an even better insight, while the latest tips at www.vienna.info and on the Vienna Facebook page keep you permanently apprised of what is currently going on in Vienna.
