Liana Finck is a cartoonist and an illustrator who has contributed to The New Yorker since 2015. She is the author of several books, including the graphic memoir “Passing for Human.” Like many of her forebears at the magazine, Finck has also published works for children, and her recent book, “Mixed Feelings,” explores the ways that emotions are often confusing—a truth for readers of any age. “Kids’ books were my first experience of art. They’re really why I do what I do,” she tells David Remnick. Finck discusses her time interning for Maira Kalman, and she shares three “deep cuts” from writers associated with The New Yorker: Kalman’s own “What Pete Ate from A to Z”; William Steig’s “C D B!”; and “Tell Me a Mitzi,” by Lore Segal, with illustrations by Harriet Pincus.
