Maybe mixing and matching patterns or cover layouts to make a mosaic of sorts. Of course, this all depends on how thick the magazines are and if you simply want to display the covers only or if you want to keep the whole magazine in tact. Maybe you could find clear acrylic organizers that would let you display one magazine while hiding/protecting the others.
