Here's a two-sided, metal dog tag featuring an image of Heath Ledger as the Joker on one side, and the Batman symbol on the other, both images taken from the hit Batman Film, Dark Knight!  The tag itself measures 1" across and 1.75" high, hanging from a 10.5" chain.  The image of the Joker standing, striking a slightly determined expression or simply waiting for your applause, is taken straight from a promotional Dark Knight movie poster!  This Joker Dog Tag is absolutely the most necessary Dark Knight...thing...ever!
