The seller didn't have much info. He said that he traded for this from an american collector (for an Metallica autograph) in approx 2006/2007. If he remembered correctly it were obtained by the US collector in a meet-and-great with Springsteen.
Jan, I took a second look at this signature and I mentioned earlier to make sure this isn't a preprint. Did you notice how straight the line is in the letter B? and the ink missing right above it. Kind of strange you can put a ruler on it.
