I'm actually not a collector, but my brother is. He recently had a stroke, so he is moving in with my family and I. He asked me to help him get his autograph collection organized, and while doing so I noticed something strange about Yvonne Strahovski's signature. The signature in the first photo doesn't match the signature in the last two photos.

He sent the first picture to Ms. Strahovski to the studio where "Chuck" was filming their second season (in 2008 I believe).

The last two pictures were sent to Ms. Strahovski at a play she was in last year.

From my research, I've gathered that the last two pictures were signed by a secretary. I can't tell about the first one though.

With the first photo being signed around 2008, since she wasn't as famous yet if that could be her real signature, or maybe she had a different secretary back then.

Any help would be greatly appreciated.
