Well, after getting a "Return to sender" on my first attempt for Paul Lo Duca, I tried again. Uncle Moe from My 2008 Topps Set Blog suggested via e-mail to try contacting Mr. Lo Duca through TVG Network where he was working according to Wikipedia. Well Uncle Moe, it worked.
At first I thought the signature was ball point pen, but after looking at it a little more I can tell that it is a fine sharpie. The "P" is a little smuged but other than that it looks great.
