I think Cameron Diaz would be considered as a good signer because people nearly always get their thing back signed. The debate is whether they're authentic or not.

On most of the things people get TTM from her, the signature looks very different from when she's signed something in person, suggesting thats someone else is signing it all for her.

Hi !
I am new to this and I have some questions about 'good signers'.
I always hear of that Johnny Depp is a very good signer,but I heard very few real success from him. I also know that Tom Cruise is a great signer, he doesn't sign TTM at all! Another 'good signer' I heard is Elijah Wood, but I think he is also a very bad signer TTM.
Opposite, I always hear that Cameron Diaz is the worst signer, I heard many successes from her TTM . Are there so many difference between TTM and IP ??
