Here's a two-sided, metal dog tag featuring an image of actor Heath Ledger as the Joker, very happily interred, on one side, and the Dark Knight Batman symbol adorning the other!  Both images are taken from the hit film that got you back into collecting comic books, The Dark Knight!  The tag itself measures 1.25" across and 1.5" high, hanging from a chain measuring 10.5" long. Cant' get enough now, can you?  Comics are good now, aren't they? That a boy.
