Kara George, a revolutionary and the founder of the Karageorgovich dynasty was assassinated in 1804 with the complicity of Milosh Obrenovich who was made Prince of Serbia by the Turks. The two families competed for control over Serbia for the next hundred years. In 1903 Alexander Obrenovich who succeeded to the throne in 1893 was assassinated and, with him, the Obrenovich dynasty ended.
     A year later a set of stamps with profiles of Kara George and his descendant, Peter I, was issued. When these stamps are viewed upside down a death mask of King Alexander, which was engraved into the design of the stamps, can be seen.
