Who was that masked man?
(San Ramon, California)
TV episodes ended with, "Who was that Masked Man" and was many times accompanied with "Maybe this will tell you who I am" and the LR would give someone a silver bullet.
This gesture was used by a number of companies to promote their products. One in particular I remember was when a sales representative from a well known delivery company came into my office and put a Silver Bullet (not a real one) on my desk and said, "Maybe this will tell you who I am." That was over 47 years ago, but I still chuckle over it every time I look at the bullet which I still have.
