Protocol droid advertisement

This protocol droid advertisement was available in the galaxy at the time of the Clone Wars. It depicted a silvery protocol droid against a blue and yellow background, or, in the case of a billboard on Coruscant, a red and yellow background. Posters were put up on the planets Coruscant and Iego, while a digital billboard version was available on Coruscant.
