Template:Unknown artist
From MediaWiki
The template {{artist?}} is used to easily tag an image for which the artist is not known. This causes the image to be placed in Category:Images by undetermined artists, where hopefully someone else will recognize the artist.
Not all images are expected to credit the artist (cartoon stills, some box art,) but when you want the image to credit the artist {{artist?}} is a quick and easy halfway-solution. At least this way other people know the image needs identifying.
