GAI is only a few years old, but the guys who run it were the top dogs at PSA numerous ealier years.
In fact, for autographs, Mike Gutierrez was alternately an expert for GAI and PSA/DNA and Mastro; James Spence for PSA/DNA and SGC; and Steve Grad for PSA/DNA and Mastro-- so there is mixing and matching of employees between companies ... It is easy for a graded autographed card to own SGC and PSA or PSA and GAI cards authenticated by the same person in the same office in the same city.
