Hey! Is it possible to purchase vertical flags/banners of various entities from the start wars galaxy? I've searched pages and pages into multiple google searches to only find licensed items or characters printed on flags/banners. Recently, Scott Kelly has been congesting my google searches and with the recent movie release, my search has become a lot harder. I'm specifically interested in government vertical flags to decorate my insurance offices. (The Empire/The Republic/etc) Like the banner flags you see at the conventions.

I took advantage of the non-member tickets on sale for the 501st party... Will I be out of place in casual attire?
