Doublemint Twins - Jayne and Joan Boyd of Hammond, Indiana, were two identical twin spokes-models who  appeared in a series of 12 Doublemint Chewing Gum commercials from 1959 through 1963 playing tennis, riding bicycles, and sliding on toboggans as they touted the company's jingle "Double your Pleasure, Double Your Fun With Doublemint Gum." When Joan became pregnant in 1963, the Boyd Twins were dropped from the W. M. Wrigley Jr. Company advertising campaign. In later years Joan worked as a receptionist in Chicago, while Jayne lived in Beverly Hills with her TV producer husband, Al Schwartz. (People Weekly 7/21/97 p. 95)
