The coolest ship in the star wars universe? I might argue against that now, maybe. But as a kid, no, there was no ship more awesome, more iconic or more badass. Did it help that Boba Fett flew it? YES.
I mean LOOK at that thing. How fucked up is that?
From Wookieepedia -
"Some people mistakenly believe the Slave I's design was inspired by a lamp post outside the ILM building. But Nilo Rodis-Jamero, an art director on The Empire Strikes Back, said that his design for the Slave I was actually based on a radar dish. It was later on when the ship was being constructed at ILM that someone pointed out that it resembled a street lamp, and from then on people just assumed that that had been the original source of the design."
I think it looks like a horses head. And how awesome was it that he flew it vertically?
The Challenge: Draw Slave 1. Examples: in flight, in combat, on the landing pad in Cloud City, delivering Han to Jabba, etc
