Not sure what became of them, the sculptor was Greg Aronowitz(sp?) He also did several SW pieces including Boba Fett ESB and ROTJ versions, Greedo, Cantina band member, Tusken Raider, and a Gamorrean Guard statue. Probably more but those are the ones I can remember. I have a Fett and Greedo and really like them. Still see them pop up from time to time.
Also did some Star Trek too. I've got the Locutus bust, think he did a Data also.
