Issue 63 of Conjunctions is themed "Speaking Volumes," and Kerry Miller's mixed media piece Brehm Djurens Liv (Animal Life) does just that in its visual imagery.
To continue the theme of speaking, subtle ceiling is credited for this cover image on issue 44 of Berkeley Poetry Review. The tumblr account, subtleceling.tumbler.com is credited to carolina, a "mixed media maker of things" from California now in Gotenburg, Sweden. The issue itself features many works that create a "collage of discrepant (and sometimes discordant) voices . . . "
This cover image for Gigantic Sequins #52 seemed a natural flow from BPR. And likewise, a natural from book designer, poet, and artist Meg Willing.
And then this nice, natural flow of images to the cover of Black Warrior Review (Fall/Winter 2014): Nager in Cyan by Summer Johnson. Sometimes, these lit mag cover features just take on a thematic flow of their own.
