Why is the cover of the comic grade missing?

It can. A mistcut cover might make the comic look less polished and could potentially lower its grade, especially if it's significant and detracts from the overall appearance.

Well, several factors matter. The detail and artistry of the cover drawing, the reputation of the comic series, and how well it catches the eye of potential readers can all affect the grade. Also, the subject matter and its appeal to the target audience can make a difference.

Maybe it's due to production issues or some unforeseen circumstances. Sometimes, there could be delays in the publishing process.

I'm not sure. Maybe it was a printing error or an artistic choice.

I think the Vox Machina Origins comic is missing because of either changes in the creative team or difficulties in getting the necessary resources for publication.

Perhaps the intended audience was assumed to understand the story without much dialogue. Or there might have been technical difficulties in including the full dialogue.

The cover of the Alf comic might have been recalled due to public complaints or negative feedback. Maybe it was inappropriate or misleading in some way.

It could be that she's trying to draw attention or express some kind of protest. There could be many reasons behind her yelling in the comic cover.

Maybe it got damaged during handling or storage. Or it could be poor adhesive quality.

Maybe it's due to a change in the creative team or a decision to rebrand the series.
