I think that there's a good chance Springsteen signed it.
Leaning towards authentic but a very rushed example so I wouldn't pay alot for it. I think baseballs should be signed with a ball point pen anyway. Springsteen signed so much during his Broadway run and there are so many Boss Autographs up on eBay going unsold right now so it's a buyer's market.
Thanks for the advice, Bruce. And I agree about ball points for baseballs too.
