The publishing industry’s annual BookExpo convention was held at New York City’s Javits Center from May 29–31, with an all-star lineup of children’s authors and illustrators. The programming featured a number of panels, parties, signings, in-booth visits, galley giveaways, and more. We’ve gathered a selection of highlights from the show.

Just after the exhibition floor opened, Caldecott Honor author Elisha Cooper took up his pencil to recreate a spread from his forthcoming picture book, River (Scholastic/Orchard, Oct.), a paean to the Hudson which, not coincidentally, runs just west of the Javits Center. Photo: Sue Corbett.

Long before he braved new frontiers on Star Trek, George Takei was a Japanese-American child in an internment camp, where he was imprisoned by the U.S. government during World War II. Here, Takei signs samplers of his forthcoming graphic memoir, They Called Us Enemy, co-written by Justin Eisinger and Steven Scott and illustrated by Harmony Becker (Top Shelf). Photo: Sue Corbett.

The skies opened up just as the Penguin Random House party started at the Bryant Park Grill, located adjacent to the New York City Public Library, but that didn’t stop the stars from coming out.

Finally, Elisha Cooper finishes his drawing.

No, just kidding. He did this painting in one hour, in the middle of a noisy convention hall. The crowd gave him a round of applause when he put down his paintbrush. The piece sold for $500 at the ABA/CBC Children’s Book Art Silent Auction, which benefitted the American Booksellers for Free Expression and Every Child a Reader. Photo: Sue Corbett.
