This encounter between two of the baddest and toughest of the DC heroes is illustrated by Andy and Joe Kubert, and if I had my choice for who would draw a fight between Hawkman and Batman, one of the Kuberts would definitely be on my short list. Hawkman's wings and Batman's capes both look fantastic, as does the muscularity on both combatants. And check out the determination on Hawkman's face. Awesome.
And I absolutely LOVE the old school chain mace!
