I've been one card short of completely my Barney 2007 USA Baseball autograph set. I was missing the blue ink/jersey card. It is a /150, but has been pretty scarce.

Here's the complete set:
There are black, blue and red autograph and autograph/jersey cards. A /2 green version of each exists, but I've never seen one and don't have any plans to add them.
