I own a store in America selling trinkets from Bali - Last month I got a letter from a Lawyer saying that the Bali Flag I'm using at my store is similar to a Sky-Streamer which has been patented. This is news to me... So now I have to proof to them that A Bali Flag/Umbul umbul has been a Balinese tradition and been used for celebration as well as ceremonious occassions for thousand of years. What I need is any articles with pictures explaining the purpose of the Umbul umbul. This article must be dated prior to January 1998. I searched on the internet, but found no article dated before 1998. Please help... Yan e-mail me your reply. Terima Kasih banyak....
