This postcard shows a model of later Kino International and Hotel Berolina. It was sent in January 1960. There is written on it: "Redesign of the city center of Berlin. Hotel Berlin Tourist with cinema and shop buildings." Read about the construction of the Karl-Marx-Allee on wikipedia.
The cinema was opened on 15 November 1963. The hotel was opened in 1964 and demolished in 1996. There had a 14-story high-rise built between 1996 and 1998. The new building is architecturally based on the former hotel and now the city hall Berlin-Mitte.
In the cinema building you can see many details of the later built one, e.g. the sculptural relief.
I find the film poster in the model remarkable. The poster is designed by Hans Adolf Baltzer, it is for the 1957 Soviet movie Don Quixote, directed by Grigori Kozintsev. It was the first feature film realized in widescreen of Soviet Lenfilm production. The poster thus indicates that 70mm films can be shown in the new cinema. I don't know if the movie Don Quixote was ever shown there.
