This striking mixed media, cut and paste collage on the cover of American Short Fiction is "The Swimmer" by B.A. Lampman, an artist in Victoria, B.C. See more of her intriguing work on her website, where she has some original works, prints, and cards for purchase.
I can't stop loving South Dakota Review's larger format publication, giving true space to the work within, as well as to the cover art. The whole publication has a kind of dark chocolate frosting feel: rich and luxurious. Lee Ann Roripaugh is credited for this cover art.
