@masoudfun1996 I had wanted to, with a gallery of all the MPAA rating screens, but I have simply not had the resources with which to do it. But LogoLibraryInc has been accumulating a good number of them, so check out his page if you want to see what many of them look like.
@Elisheval Good guess, and very observant. But this stamp is actually a 1908 issue from Austria, used to buy newspapers. The face is that of Mercury. The Scott Catalogue number for it is P15. Worth only the most minimum value, but a nice stamp anyway.
