1. Cover art: Cover art from various items, for identification only in the context of critical commentary of that item (not for identification without critical commentary).

Unacceptable use

8. A magazine cover, to illustrate the article on the person whose photograph is on the cover. However, if the cover itself is the subject of sourced discussion in the article, and if the cover does not have its own article, it may be appropriate

J Greb using the cover of a magazine that is not the subject of the image is unacceptable by wikipedia guidelines as I have tried SO HARD to make him understand the past.
