ARNOLD MOSS from STAR TREK (autographed letter and envelope)

This is a letter (with envelope) from the character actor Arnold Moss. He was a radio and TV actor who played tons of supporting roles and is best known for his role in the Shakespearean actor in the STAR TREK episode, "The Conscience of the King." He passed away in 1989 so finding a legit autograph (before the days people really set about collecting autographs) is difficult. Here you go!

First come, first serve.
