I've seen one of these jackets in the background on one of Steve Sansweet's "Visits to Rancho Obi-Wan" mini-series things on Star Wars.com Hyperspace.  It's in really good condition.  These things are pretty old, I think.  About early to mid-ninties, if you can call that old.  I've been looking for one of these things for a while, but I've never been able to find any info for them, or any pictures, up to this point.  They used to have them for sale in the Star Wars Insider many years ago, but that was back before I was really into Boba Fett, so I never bothered.  (Kind of like the Star Wars Insider Slave 1 print that you can't find anywhere now--still searching for that one, too).  It was back around the first Star Wars Celebration, in Denver.  I remember seeing them for sale along with the some other jackets they had.  One of my buddies got a Darth Maul jacket kind of like this for him and his wife, when we were at the Celebration. 

I had never heard or seen anything about the helmet, though.  That's a neat extra bonus.  I wonder what the reserve price is?  I remember the Darth Maul jackets selling for about $300 or something like that.  Pretty pricey.

Very interesting, he said that it came from the Lucas archives.
