More than any other cultural or political figure of the past half-century, Big Bird can be considered the great uniter. No other teacher has influenced a wider swath of children — spreading the Sesame sermon far and wide, regardless of nationality, ethnicity, race, or economic bracket. “Somebody Come and Play”: 45 Years of Sesame Street is the NYPL’s new, comprehensive send-up of the public-television phenomenon, filling the Lincoln Center Library for the Performing Arts with 250 items related to the show and its production, including many of its stars: The original Elmo, Bert, Ernie, Count, and Oscar the Grouch will be on display, along with other televised Muppets. See iconic props (“rubber duckie, you’re the one…”) and pose with replicas of the lamppost and front steps of 123 Sesame Street. For a more in-depth look, check out behind-the-scenes artifacts like original design sketches and style guides, scripts, animation cels, and orchestrations for classic musical numbers, such as “C Is for Cookie.” Lectures and workshops (including a muppetry master class) for kids and adults will take place on-site throughout the exhibit’s run.

Mondays-Saturdays, noon. Starts: Sept. 18. Continues through Jan. 31, 2014
