I have had this photo since 1978. I was 14yrs old back then when a guy I knew gave it to me because he knew how much of a fan I was (I started loving the band at  age 11 when Physical Grafitti was released and i got it from my uncle for Christmas). The photo is actual Kodak paper so I am pretty sure it is a one of a kind. I have kept it with me throughout my life, now at 48yrs of age. A couple of years ago I was at the Robert Plant & the Strange Sensation show at the Molson Amphitheatre in Toronto. My buddy Howie knew a guy who was able to get me backstage, in a line of people that Robert was going to have to walk by after he finished an interview nearby....... Sure enough Robert came out of a tent and was at the  far end from me. Holy smokes! there he was.... Women were going wild as he signed his name to stuff, and posed for pictures. As he got closer to me he turned to leave. I yelled, `Robert!...please can you sign this``...he turned and came back over to me, looked at the photo, smiled hugely, grabbed my sharpie, and signed it. I wish I could have at least said something but  I was unable to speak.....the guy that was on my wall all these many years, in posters, and who I have listened too to the point of him feeling like a good friend was standing right in front of me and I could not utter a word. I just wish I could have said thanks for all the music......I had to share this with my fellow Zep fans ...cheers, Richard...P.S.-He was very nice to everybody and that was great to see.....God Bless Led Zeppelin
