Yeah, I had been wondering whether it was from the early Zeppelin days or if it was a Yardbirds-era photo. Then my boyfriend said he got that guitar after LZ formed, and later, it got stolen (not sure what year). Also, in some versions of it, you can see that he has long hair. So I'm guessing it's from '69 - '71 or something like that.
Anyway, it's my favorite picture of him. And it's a beautiful Les Paul.
