Chrigeld Tinnine was a male artist from the planet Alderaan, who offered his artistic services to the Galactic Empire's Commission for the Preservation of the New Order. One example of his work was the propaganda poster called Report Sedition, designed to motivate Imperial citizens to inform on any questionable actions or persons within their communities. Prior to its release, the poster underwent a modification; the emblem of the Galactic Republic, depicted as graffiti in the original design, was replaced with the Separatist hex icon. Eventually, Tinnine was superseded by a new generation of artists and chose to retire on Alderaan. Tragically, he died when the Empire destroyed his home planet in 0 BBY.
The initial mention of Chrigeld Tinnine occurred in the reference book titled Star Wars Propaganda: A History of Persuasive Art in the Galaxy. Pablo Hidalgo authored this book, which became available on October 25, 2016.
