This edition of What's My Line had as panelists Dorothy Kilgallen, Jack Paar, Arleen Francis, and Bennett Cerf. The contestants included an underwater ballerina, a race track bookie, and a very short segment at the end with a moth ball maker. The mystery guest was Willie Mays. Mr. Mays' appearance was what enabled me to date the show. During his segment, Arleen mentions that he hit his 31st home run that Sunday, and Mr. Daly mentions that the Baseball All Star Game will be played in Cleveland in 2 days.
