I cant comment on the Springsteen signature itself b/c the back end is in the darker portion of the LP, but the proof photo doesnt look like the LP above. Thats not to say the proof photo was supposed to depict this signed LP, but it seems like it was. The thing i noticed on the proof photo was the very light border surrounding the LP being handed to Bruce. The LP pictured above doesnt seem to have that light border. Their could be another explanation for this though.
The signature isnt stacked like some Bruce's i have seen, and the T goes up awfully high, and the R in Bruce is very large, but it may just be a rushed signature. Hopefully members better on Bruce will comment.
