Description: Publicity photo from the television program The Munsters for Halloween. Pictured from left: Al Lewis (Grandpa), Beverley Owen (Marilyn), and Fred Gwynne (Herman Munster).

Date: Not dated. Beverley Owen played the role of Marilyn for the first year of the program only; she was replaced by actress Pat Priest after that. The series began airing in 1964 and the publicity information mentions this is a popular new program. This would have to be from 1964, as Owen was no longer in the cast by 1965.
