There is a Vulcan Sash from TOS on eBay. You can see it here.
Star Trek TOS Production Made Vulcan Sash as seen in the episode “Amok Time”. Was originally purchased from William Theiss (Costume Designer for TOS Star Trek). Sash is 5 feet long and 5 inche wide. COA from Screen Used is included.
I like this item and think it is a great piece of TOS history. It says it came from Bill Theiss, which is solid. I think that things like this, that you can pick up under $ 1,000 are great TOS buys.
