Gusztáv, also known as Gustavus, was Hungarian series of animated short cartoons for adults. It was extremely popular in Eastern Europe, where it has achieved cult status. It ran from 1964-1977.

Each episode tells an adventure of the main character, Gustav, related to the gray realities of urban life. Characteristic feature of the show was that episodes were independent: for example, Gustav is sometimes a bachelor, sometimes has large family. In Eastern Europe and Yugoslavia the episodes were broadcast on TV in the 80s, usually as airtime filler. The series was also broadcast in Western Europe and even in New Zealand - because it was not using language, other than gibberish sound, it was able to easily transcend boundaries.

The series covers the events of the ethnic clashes in Târgu Mures after the fall of the communist regime. The author has arranged the written and film material collected by the Dr. Bernády György Foundation in chronological order. The archival photos showing the important events of the five days, the moments that created the revolutionary atmosphere, are complemented by the recollections of Hungarians and Romanians, and official statements.
