I dunno guys. It could be Dragon and Tiger, but the way the two figures intertwine, I just don't feel it's cut-and-dry. The dragon and the tiger, in Asian cultures in general, represent supremacy in heaven and on earth, respectively. As I understand it, the dragon is regal, wise, and intellectual. The tiger is fierce with indomitable strength and spirit. But, they represent different spheres of influence and different qualities, for lack of better expression - the dragon reigns supremacy in the heavens and the tiger on earth. So, the dragon is the emblem of the royal family and the tiger usually the emblem of military commanders of the highest rank (at least in the Chinese and Vietnamese cultures). In depictions of struggles between Dragon and Tiger, I would think they represent power struggles between the Emperor and his military. I would be hard pressed to think of a situation, from a historical point of view, when the Dragon and the Tiger would be so intertwined and harmonious as depicted in Mike's menuki. Personally, I don't think they are Dragon-Tiger, but Dragon and something else. Don't know what, though. I am probably way off course here, so, shoot me down...
