A previously undocumented variation of Led Zeppelin's album PHYSICAL GRAFFITI, customized by Atlantic/Swan Song Records circa 1975 for now defunct Chicago Radio Station WMET. This was discovered in the collection of the former editor of music industry trade publication RADIO & RECORDS (read the complete story on our blog at www.recordmecca.blogspot.com ). The letter of authenticity, from former R&R Editor and USA Today Music Editor Ken Barnes gives the short version, and reads: "To whom it may concern: This letter is to authenticate an original, sealed copy of Led Zeppelin's album Physical Graffiti with the call letters of Chicago radio station WMET and alternate artwork visible in the windows of the album cover.(br)I have had this album in my collection for decades, and in fact until Jeff Gold found it among the other Zeppelin albums (mostly promo copies) in my 30,000 LP collection, I never noticed this was in any way different from the regular issue of the album.(br)I very likely obtained this album while working at the radio industry trade publication Radio & Records, around the time the album was released. I was an editor at Radio & Records and received thousands of promotional albums from record companies, while working at R&R and writing about music for various publications over the years, most recently as music editor for USA Today.(br)Sincerely, Ken Barnes." Barnes is pictured in the 3rd photo, holding the album just after its discovery. Sealed, mint condition, and guaranteed authentic with no time limit. The only known example of this Led Zeppelin rarity. SOLD
