In the early 1970s, Sesame Street producers lured Oksner from McCaffery & McCall to join a select handful of leading admen and educators who were tapped to develop the revolutionary children's educational show.
After leaving Sesame Street, Oksner returned to advertising, creating unusual PSAs for nonprofits such as The American Lung Association using celebrities like Sid Caesar, the Smothers Brothers, Pearl Bailey and Cybil Shepherd.
