I picked this up at one of the Vulkons, shortly after "Next Generation" started airing on TV. This isn't one of the cheapo pins, it's brass, with gold and silver plating.

These are still selling at many places for $20, or so.

After a while, I got one of the "sound boards" that went inside your jacket to add the sound effects to it, but rarely used it.

I did own one of the Light and Sound Communicator Badges manufactured by Playmates, at one time. I forget if I still have it...
