I wonder why she wouldn't sign that dude's poster. Presumably signing things is one of the primary reason she goes to cons.
It's long been known that she doesn't like that cast photo and would prefer that it not be out there. I can see her point.
She likes this one
, and doesn't like this one
. And why should she? She's a part of the main cast and they release an official photo with half of her face obscured? It should never have happened.
I remember back several years (decades), when someone would bring the offending pic up for signature, she would exchange it with the preferred one out of her own stock. I thought that was a good way to handle it. But given the presence of the other signatures on the pic, she should have been gracious enough to swallow her pride and sign it.
