the via venue one on the right is genuine,the other is a sec

I believe they are authentic. :-)

What do you think?

I claim no expertise, but my opinion would be that given that she's an artist and not a machine, I'm inclined to believe that they are both written by the same person. (And if she is secretarial then she is known to be sharp and bright enough to get her secretary to sign the VV ones as well as the TTM). Is it me, or is the dedication on the TTM written with a different pen to the signature? I wrote to her a couple of weeks ago, tending towards the view that she does sign them herself, but suspect that I will never really have any certainty about it assuming I get a reply.

I've had autographs from people IP at the same event where the differences between them have been greater than the differences between those. I went to an event a few weeks ago where a Very Famous Drummer signed three things for me and two for a friend who came with me, and if I were to post images of them on here no-one (including myself) would believe them to have been written by the same hand.

I read on is it real that Debbie Reynolds TTM are sec which I found very surprising. I decided to try Debbie VV and see if the sig was any different.

VV autograph is on the right - normal TTM is the left

Here is the comparison.
