I am happy to provide the date, location and provenance backstory of the signed item within ebay rules. Two experts which are pledged to provide an unbiased independent opinion; authenticated and examined the item for double verification. My uncle worked as a radio Disc Jockey, and collected autographs for 70 years for all music genres. (I also worked in the 1980's as a radio DJ at MSOE.EDU; playing all music genres). I inherited my Uncles autograph collection which was almost as large as my own autograph collection that I have been collecting from sellers and artists for 55 years. We loved going to live events across the USA and Europe; or requesting autographs from singers and musicians at radio stations or promotional events mailers.
