2GB

A super-mini, one inch sticker from radio station 2GB in Sydney, Australia.  2GB began broadcasting in August, 1926 at 950 on the AM band and was originally operated by an entity known as Theosophical Broadcasting Station Pty Ltd.  Theosophy is a blend of eastern religion, scientific inquiry and a belief in the universal brotherhood of man and was a precursor to the New Age movement.  The call letters refer to Giordano Bruno, an Italian philosopher much revered by Theosophists.
2GB currently broadcasts at 873 AM and carries a News/Talk format.
