Rosebud is the sled.
Jack is the Candidate.
Darth Vader is Luke's father.
Thanks to Ger, another mystery is solved.
All three of the watercolors that ultimately gave rise to the images in Epic are originals... but not the originals that were published (Cerebus on the throne, young Cerebus, and the recently sold Prime Minister Cerebus); well, kinda sorta.
The story of the color mismatches is the mirror image of the Moon Roach story, which I guess places it in the ALT universe.
In each case, the pre-coloring black and white version was copied, and those copies were then colored, in particular, for their appearance in Epic. Those original production versions are... somewhere. Maybe tucked away in a file drawer at the off-white house, maybe in some Epic editor's file cabinet.
The black and white original drawings, once copied for their Epic coloring, were then independently colored, and these are the ones that we all have. So in the Epic spread, it is otherly-colored photocopies of the original art... so these ones that we have did NOT appear in Epic, but they are the best originals to have.
Everyone thank Ger... and wish him well as he hauls the boat out from its wintertime berth and launches the 2010 sailing season.
