I think it would be cool if Marvel brought back the corner box on their comics, to both spruce up their general trade dress and make it easier to identity titles on the shop shelf where they may be obscured by other comics. My idea for an updated version of the classic box would be to have a logo showing any team affiliation (or if they are more of a solo character then that individual’s logo, such as the Daredevil example above) and to colour code lower part of the box to make it fit nicely with the cover image (such as on the Hawkeye example).
