Protocol droid advertisement/Legends

This protocol droid advertisement was available in the galaxy at the time of the pan-galactic conflict known as Clone Wars. The advertisement depicted a silvery protocol droid set against a blue and yellow background. A billboard on the planet Coruscant showed an alternate design, in the form of a red and yellow background. Posters were put up on planets such as Coruscant and Iego, while the digital billboard version was available on Coruscant.
