Lucasfilm 2004 product. Voice processor transforms speech from mic in helmet. Other buttons trigger [breathing] or stock quotes like "Don't make me destroy you". Three fresh AA batteries. Big enough to fit on my adult size 7 1/4 head with small eyeglasses on. Just in time for Halloween, or whenever you are feeling the Dark Side. I used it to answer Trick or Treaters  at the door. Just add a black cape and a light saber (NOT INCLUDED).!
