A member of the Star Trek Prop, Costume & Auction Forum pointed out this ad. It is for a set of patches that the seller claims were used on Star Trek.
I informed the seller that they were not in fact used on the set, and most probably used in the Universal Studios "Star Trek" Ride from the 1990's. When informed about this, the seller got nasty with me, claiming I had no idea what I was talking about and that I was being "vulgar" by questioning her auction.
I know you are all smart enough to avoid sellers like this, but just remember, "Be careful out there!".
