I know almost nothing about comics. BUT,
the guy posted his inscription on the internet and if he hadn't done that no one would have ever known (and maybe that would have been ok). because walking up to an artist and handing them a book isn't that big of a deal. but now, every time the yellow hat guy shows up at a con he's going to be chastised.
ugh. i can't even finish this.
i think what he did (the posting it on the web part) is reprehensible.
