Dick York was in an episode of Alfred Hitchcock entitled The Doubtful Doctor who goes 2 years into his past and his life is turned upside down. He has a scene where he purchases some baseball cards with some kids. He later returns to the present with wet baseball cards in his pocket. He had tried to drown himself. The cards are from the fifties
Also, the Post Cereal box in the Sandlot with cards and Mickey Mantle on it. I believe Doctor James McAvoy supplied the box for the movie. here is link with a picture.
