This one’s pretty interesting. Those markings weren’t on the helmet in the finished film so I’m guessing this is from a costume test or something like that.
Back in the day the Boba Fett fandom knew all about how his armor changed color between films, and about various costume tests, both this one and the all-white version. Interesting how that sort of thing gets forgotten generationally.
Always fun to see Jim Henson in SW photos.
