Mounting slabbed autographs
 

I've been curious about the possibility of taking a slabbed/authenticated index card or cut and having the slab mounted in a frame with a b/w 8x10 above it. I see a lot of cuts and index cards mounted with a photo and the entire mount has been authenticated, but with a slab in the mount.

Is mounting the slab possible? Has anyone created a mounted piece in this fashion?
