Cromwell and Fox played Holmes and Watson respectively in an award winning commercial for BPA's "Cold Facts. Hot Ideas." appliance efficiency promotion campaign in 1986.
Outside of educating the public about fridges, Cromwell has appeared in such major motion pictures as "Babe" as well as "Star Trek First Contact" (Where the autographed card is from).
Fox is perhaps best remembered from TV as the warlock physician Dr. Bombay on "Bewitched" and the inept British Colonel Crittendon on "Hogan's Heros". His autograph is already within the collection for his role as Dr. Watson in the 1972 version of Hound Of The Baskerville with Stewart Granger as Holmes.
