To be honest, I'm not seeing any signatures that look authentic. Mortensen, Astin, Bean, Wood all look way off.
Also, in general, when you see a poster perfectly signed like this, all in the same pen and neatly (one name under the other), that's pretty shady - to put it mildly. I don't recall a signing event where just aboout all the cast members signed (including Holm, Mortensen, Tyler, etc), and this doesn't look like it was signed on the street.
Regardless, if you look closely, you can start to recognize that the signatures were signed my the same hand as well.
Thanks for your opinion! I'm new to this so all of your tips is greatly appreciated.
Agreed, these were all signed by the same hand.
