Hey guys. 

I've found a signed photo of former Vice President and Democratic candidate Joe Biden on eBay and I'd like to know if the signature on it is authentic or pre-printed / autopen, etc. 

The seller says in the listing's description that it was sent to him from Mr. Biden's Senate office in Delaware (or Washington, it's not made clear, but both Delaware and Washington are given as the office's locations like this; 'was sent from his office in Delaware-Washington'). The description says that Mr. Biden was a US Senator at the time, so I'd put the date somewhere between 2007 and 2008. 

The ink looks good for a hand-signed signature, but I don't want to have high hopes yet, because obviously it could easily be an autopen or secretarial. But I'm no expert on Mr. Biden's signature, so if anyone of you could help me figure out its authenticity, I'd greatly appreciate it. 

Here are two pics of the signature as posted on the listing. All comments are welcome. Thank you!
