In the 4th episode of season 1 “Lucy Thinks Ricky Is Trying to Murder Her” Lucy (Lucille Ball) sees Ricky (Desi Arnaz) mixing something into her drink and thinks he is trying to do away with her.
Ricky is seen using a cocktail shaker set that would look good in a mid-century style home bar, and was a popular item for 1950’s home entertaining. The picture above came from an ebay auction for a similar cocktail shaker, it is not an original Desilu prop but it is vintage and in fine condition, and exactly like the one on the shelf in the screen capture below from “I love Lucy” Season One, Episode 4.
