AS A CHILD, Roz Chast found a warm home deep in the world of words and pictures. And when the New Yorker cartoonist puts pen to paper herself, she now creates worlds that seem to spark recognition even as they summon our imagination.

It is with those gifts that Chast has created the newly released poster for the Library of Congress’s 2017 National Book Festival (of which The Washington Post is a charter sponsor).

“I was a book-loving kid, and I’m a book-loving grownup,” Chast tells The Post’s Comic Riffs. “That’s because every book is like a parallel world which you can step into the minute you open its cover.”

Books are also great because “if you decide, ‘This world is not for me,’ you can step right out and pick up another one,” says Chast — the author of the award-winning graphic-novel memoir about eldercare, “Can’t We Talk About Something More Pleasant?” — who will also appear at the festival.

The library was naturally thrilled with Chast’s “fantastic” work.

“As the poster proclaims, books are meaningful, magical and necessary for everyone,” Librarian of Congress Carla Hayden says. “Roz captured the spirit of the book festival in a wonderful way, and we’re excited to be able to show it off.”

This year’s festival will be Sept. 2 at the Walter E. Washington Convention Center.

(Disclosure: Comic Riffs is an adviser for the programming of the festival’s Graphic Novel Pavilion events.)
