Obviously the entire thing is duplicated, but the flames were originally done by a reknowned airbrush artist named... shit. I forgot his name. Let me call my bro-in-law- he's got a ton of original crap from this guy...
EDIT: here you go: http://www.killerpaint.com/flash/killerpaint_flash_index.html
His name is Mike Lavallee and his work has been on American Chopper, Monster Garage, etc. He's pretty much the best flame job artist in the world.
My brother in law has entire refridgerator flamed by this dude.
