I think this is the very picture that got my long-hair fetish started or at least finally made me realize that I have such a thing.
It was on the cover of a German youth magazine in late 1973 (I think), and I must have been staring at it back then in shock, fascination, and disbelief, all at the same time, not knowing what to think or to do as a 15-year-old in front of our small-town store where everybody knew me....
Thank you very much for posting, although it also brings back memories of years of that terrible insecurity I was going through.
