This is a copyrighted image that has been released by a company or organization to promote their work or product in the media, such as advertising material or a promotional photo in a press kit.

The copyright for it is most likely owned by the company who created the promotional item or the artist who produced the item in question; you must provide evidence of such ownership. Lack of such evidence is grounds for deletion.
