Sesame Street creator Joan Ganz Cooney was on hand at Sesame Workshop yesterday as the New York City mayor’s office proclaimed Nov. 10, 2009, as Sesame Street Day, and placed a temporary street sign at 64th and Broadway across from the workshop to honor the 40-year-old show. The cast and crew were there, as well as President and CEO Gary E. Knell. The Workshop staff jammed elevators to attend, wearing bright T-shirts and party hats for the occasion, top.
