Would it be acceptable to create wiki entries for promotional comics that are, for example, included as a bonus in the now-defunct Wizard: The Comics Magazine?
For example, DC released Batman issue 616A for inclusion with Wizard issue 0. The first page explains that it is set between Batman #616 and #617, and featured an unique 9-page story set during Hush. So could I create a Wiki article for this? And if so, would it be a separate volume, or would it be added to Batman? Unfortunately, it doesn't have the small-print minutia commonly found in comics.
