Family guy season 3 (Volume 2) signed by creator Seth MacFarlane. Also signed by one of the other makers of the show, but I can't recollect who it was.

I personally had this signed by Seth MacFarlane at an event held at the Virgin Megastore in New York, many years ago. Very much authentic.
There is some wear to the case, but not where the signatures are (see pictures).
All discs included and tested.

Also selling Volume 1 (seasons 1 and 2), NOT signed. I could so combined shipping.
