As you can see the conventions between these images are central mastheads that are placed at the top of the page with a close up main image at the centre of the page or a mid/long shot in the centre of the page, usually the anchorage text is placed bellow the image or over it. With additional information littering the sides of the page. I think out of all of these the Interstellar and the Shock Horror magazines are the most impressive due to their close up intimacy and with them keeping it simple.
