The thing that never fails to impress me about Kirby's version of the Hulk is the power and weight he gives the figure. Recent, far more overtly muscled, interpretations of the Hulk don't look nearly as 'strong' to me. Rather than huge biceps and a six pack Kirby seemed to emphasise the hands and feet and tree trunk legs.
Yes, totally agree with you on that, Rich. For me, Kirby's Hulk has always been the definitive version.
