It would look like this!
Some where, out there, in the depths of the Multiverse, there is an alternate reality where Gary Gygax was best buds with Jack "The King" Kirby!
In that wondrous world, True Believers, Kirby illustrated Dungeons & Dragons with all the majesty and hallucinatory phantasmagoric wonderment that only he was capable of!
Consider well, oh my brothers, (and Timeshadows), the mind expanding force of fantastic illustration, and think on what might have been the path of Dungeons & Dragons had this exotic world been ours!
I'm a bit punchy tonight. please forgive my hyperbolic hyperbole.
