I think we have some duplicate/extra issues with the Donald Duck Halloween comics.
First, Donald Duck Halloween Mini Comic 2008 is also listed under Walt Disney’s Donald Duck: Halloween Ashcan 2006.
Next, these mini comics were also sold in multipack bundles. I guess it doesn’t hurt, but it seems odd to index that bundle for Halloween ComicFest 2017 (Donald Duck’s Halloween Scream!).
Lastly, we have Donald Duck Halloween Mini Comic Bundle 2008. That uses the cover from the 2011 ashcan (Walt Disney’s Donald Duck: Halloween Ashcan 2011) but the date from the 2008 ashcan (Donald Duck Halloween Mini Comic 2008). Either way, I would recommend deleting the bundle pack altogether.
