This was a really cool find. This mug was given out to the season 3 sound department crew as a gift. I am not sure when these mugs were presented to the crew. I also am not sure if its legit as I have yet to see any others. Though I do believe the crews were given gifts during the production.

It has the list of names of the sound department on one side. I checked IMDB and the names on the mug are affiliated with the sound department during season 3. It was shipt from Studio City, Ca. So it is really likely that this was an actual gift.

Regardless of whether or not it is a real gift it is still pretty cool. It was also part of the first batch of items for this collection. I am unsure if it was previously used but it currently is not being used.
