Our Led Zeppelin Chicago newspaper from cancelled 1980 Chicago Stadium concert due to the death of John Bonham on the very same day the tickets were to be sold mail order 9/25/1980 was trademark violated with use of this feather symbol never on original ad. Slick operators (know who they are) then quickly trademarked altered ad giving idiot algorithms fuel for shutdowns of real ad as we never copyrighted ad during our multi decade usage. Karma may very well be a bitch here, hope so.
