The Comic Reader was a late 1960s-early 1970s newszine/fanzine, available at comic conventions and by subscription.
The covers were almost always exclusives, either pieces done to promote current projects (a Manhunter cover by Walt Simonson during the character's revival in Detective Comics) or unpublished work like this one that editor-publisher Paul Levitz felt deserved exposure to an appreciative audience!
