The name Papiermark (   ; English: "paper mark" , officially just "Mark", sign: ℳ) is applied to the German currency from 4 August 1914 when the link between the Goldmark and gold was abandoned, due to the outbreak of World War I.
 In particular, the name is used for the banknotes issued during the hyperinflation in Germany of 1922 and especially 1923.
BerkShares is a local currency that circulates in The Berkshires region of Massachusetts.
 It was launched on September 29, 2006 by BerkShares Inc., with research and development assistance from the Schumacher Center for a New Economics.
 The BerkShares website lists around 400 businesses in Berkshire County that accept the currency.
 Since launch, over 7 million BerkShares have been issued from participating branch offices of local banks (as of Nov. 2015 eight branches of three different banks).
 The bills were designed by John Isaacs and were printed by Excelsior Printing on special paper with incorporated security features from Crane & Co..
 BerkShares are pegged with an exchange rate to the US dollar, but Nick Kacher of the Schumacher Center has discussed the possibility of pegging its value to a basket of local goods in order to insulate the local economy against volatility in the US economy.

 It is the backbone of one of the best performing public transport systems worldwide according to UITP (International Association of Public Transport) in June 2009.
 More than 1.3 million passengers rode the Vienna U-Bahn every day in 2009, and 567.6 million passengers used the U-Bahn in 2011, which declined to 428.8 million passengers in 2013.
 The network is undergoing expansion and rolling stock renewal.
 Since 1969, 200 million euros have been invested annually in the extension of the Vienna U-Bahn.
The Reichsmark (] ; sign: ℛℳ) was the currency in Germany from 1924 until 20 June 1948 in West Germany, where it was replaced with the Deutsche Mark, and until 23 June in East Germany when it was replaced by the East German mark.
 The Reichsmark was subdivided into 100 "Reichspfennig".
 The Mark is an ancient Germanic weight measure, traditionally a half pound, later used for several coins; whereas "Reich", that is "realm" in English, comes from the official name for the German nation state from 1871 to 1943, Deutsches Reich.
The Goldmark (   ; officially just "Mark", sign: ℳ) was the currency used in the German Empire from 1873 to 1914.
 The Papiermark refers to the German currency from 4 August 1914 when the link between the Mark and gold was abandoned.
Viennese Girls (German:Wiener Mädeln) is a 1945 historical musical film directed by Willi Forst and starring Forst, Anton Edthofer and Judith Holzmeister.

 It was the third film in Forst's "Viennese Trilogy" which also included "Operetta" (1940) and "Vienna Blood" (1942).
 The film was finished in 1945, during the closing days of the Second World War.
 This led to severe delays in its release, which eventually took place in 1949 in two separate versions.
 One was released by the Soviet-backed Sovexport in the Eastern Bloc and the other by Forst.
Messter Film was a German film production company which operated during the silent era.
 It was founded by the German film pioneer Oskar Messter who already owned a chain of cinemas.
 It was based in Berlin which had energed as the centre of the German film industry.
 Messter quickly established itself as dominant force in German production, particularly during the boom years of the First World War when foreign films faced many restrictions in Germany.
 Messter played a prominent role in the development of the German feature film, moving away from the shorter running times which had been standard in the early years of cinema.
 Messter also produced its own newsreels.
 In 1917 the company became part of the large conglomerate Universum Film AG (UFA) which brought together many of the leading German companies in a single, powerful organisation.
 Messter continued to produce films as an individual unit of the UFA umbrella.

 However, the librettists added the element of combining love and politics to the French comedy plots.
 It premiered in Vienna in 1882.
 A German film adaptation, "The Beggar Student", was directed by Georg Jacoby in 1936 and a West German film adaptation, "The Beggar Student", was directed by Werner Jacobs in 1956.
