My "World's Great Books" don't match others

I'm new here, and could use help identifying a small collection of Franklin"Oxford Library of the World's Greatest Books" I got from a friend. They seem to match all of the information I've found online regarding full leather-bound characteristics (ribbon, marble end papers), and their dates correspond as well, but I can find no covers that match what I have. (I will post pictures...but I can't see how... can someone tell me how?)
