"Miss Theelin" was a beauty competition, broadcast live, that took place in the winter. It was open to Theelin women. In the closing years of the Galactic Republic, promotional posters for the event were displayed across the galaxy. These posters, in shades of purple, orange, and gray, each depicted a Theelin woman and included Aurebesh writing. These posters could be found in places like Trueping's, a bar on the planet Coruscant, inside a Turtle Tanker starship, and at the spaceport of Pons Ora on Abafar. During the Galactic Empire's reign, Garazeb Orrelios, a Lasat, had a "Miss Theelin" poster attached to the wall by his sleeping quarters on the freighter Ghost.
The "Miss Theelin" poster, designed by Randy Bantog, debuted in "Deception," episode fifteen from the fourth season of the Star Wars: The Clone Wars animated series, considered canon. It was initially broadcast on January 20, 2012. This poster was used repeatedly in the series and later made another appearance in Star Wars Rebels.
