Holiday Express: All Aboard to Richard Scarry’s Busytown

A holiday favorite returns to the New-York Historical Society this season—reimagined to celebrate the 100th birthday of Busytown series author and illustrator Richard Scarry. Holiday Express: All Aboard to Richard Scarry’s Busytown (November 1, 2019 – February 23, 2020) showcases artwork and graphics of Scarry’s characters like Huckle Cat and Lowly Worm from publisher Random House Children’s Books alongside more than 300 objects from the Jerni Collection’s antique toy trains, stations, and accessories. Using Busytown stories and characters, dynamic displays explore the workings of the railroad, the services it provides, and the jobs required to keep people and goods moving. An assortment of kid-friendly activities, story times, and crafts accompany the exhibition throughout its run, welcoming families into the world of classic toys and trains. Richard “Huck” Scarry Jr., the son of Richard Scarry, will make a special appearance on December 14 and 15. Holiday Express: All Aboard to Richard Scarry’s Busytown is supported by Bloomberg Philanthropies. Additional support provided by Random House Children’s Books.
