This discussion is aimed towards helping other collectors determine the potential authenticity of their own TTM returns from Hollywood celebrities, primarily by helping to identify ghost signatures and autopens. For me, pre-prints are fairly easy to determine, followed closely by autopens. Ghost signatures can get tricky sometimes. Photos or links to photos of your items would be helpful. Also, if you would just like to list celebrities that you know commonly send out these types of items, feel free to add that as well!
