A thin case that holds original artwork?
 

Has this been invented yet? A thin spined case with slightly wider front and back covers so that your typical amaray cover can be placed in it without you having to cut it. And yes, I already know about discsox before some replies with that. I mean like a slim case that will hold the artwork from a standard amaray.

I've never seen one. They'd stick out further than regular keepcases in a shelf, wouldn't they?

Yeah, but not by much. I can see where that would be a problem for some people but my shelves are about 8 inches deep so it would not be a problem. BTW canary, salutations from middle TN.
