Previews
From Tardis Wiki, the free Doctor Who reference
Previews is an American monthly magazine and catalogue published by Diamond Comic Distributors, which showcases upcoming comic books, graphic novels, and other pop culture collectables.
The publication has, naturally, advertised countless Doctor Who items within its pages throughout its run, from the American comic book runs by IDW Publishing and Titan Publishing Group, to other collectables.
The 427th issue of the magazine is particularly notable, in this regard, for advertising the then-upcoming launch of Titan's Doctor Who: The Fifteenth Doctor series as its main cover story.
