Fox has re-released some titles with exclusive Comic-Con artwork. They also come with a limited edition numbered lithograph (at least the first 100 ordered online). I have seen both the covers and lithographs in person and they both look way better in person that in the images below.
Additionally they have a limited edition of Rise of the Planet of the Apes in a Caesar bust. This is the 3D/BD/DVD/DHD version with a 32 page booklet. It looks fantastic in person! Its available for pre-order at Comic-Con and online at Fox Connect.
Here is a pic I took on the floor. The detail is amazing!
