I have a special place for picture books that incorporate art history in interesting ways. But just when I thought I couldn’t be surprised anymore, along comes a new addition to the genre that really took some new turns. I caught up with author-illustrator Brian Lies (best known for his Caldecott Honor Book, THE ROUGH PATCH) to learn more:
Me: Congratulations on your stunning new picture book, CAT NAP (Greenwillow Books, Sept. 2025)! I’ve seen characters step into artworks before – but not like this! What inspired you to create this book?
Brian: Thank you, Jonathan—and you’re right, there have been books with characters interacting with artworks before. I just haven’t seen one where the artworks the character visits are all near-forgeries of the originals, created in their original materials.
The book started with our part-Russian Blue / part Siamese cat disappearing one day and we couldn’t find him anywhere. He returned some hours later, completely nonchalant, with his whiskers covered in cobwebs. Where had he been? We joked that he’d found a wormhole in space and time, and maybe had gone back to ancient Egypt, where cats were revered. From there, it expanded to the idea that he’d had an adventure moving through artworks from a variety of cultures at the Metropolitan Museum of Art in NYC, and baked into it at the beginning was: I want to see if I can create near-forgeries of all of these artworks!
Me: Not only is it a fun, whimsical journey through art history, CAT NAP is the first book in a while where I had to keep asking myself, ‘How the heck did he do this?’ So: How the heck did you do it?
Brian: I’ve always made things with my hands, so some of the materials and media were familiar to me—stained glass, for instance, which I learned to do in high school. But some techniques were new to me, and I either experimented with materials or learned from “YouTube University,” picking up techniques such as gilding. I bought a digital book on traditional stained glass painting, and it came with a number of tutorial videos, which were extremely helpful. Doing the final artwork for CAT NAP was a nine-month immersion in silicone mold-making, plaster casting, wood bending, wood carving and more—and it was an absolute blast. I don’t think I’ve enjoyed making art this much since high school, when everything I tried to do was new to me.
Me: Beyond the artworks, the living room is filled with many sumptuous – and perhaps symbolic – details: the red couch. The books. The lamp! Are these based on real objects? Any personal connections you’d like to share?
Brian: I’ve always been drawn to Arts & Crafts furniture, ever since I first visited the library which my book Bats at the Library is set in, the Riverside (IL) Public Library. It was my Dad’s childhood library, and I just loved their Arts & Crafts furniture. Most of the objects on the plate rail along the wall are things we have around the house, minor antiques…
Me: Any tips for younger authors and illustrators – digital natives – who may be interested in using more non-digital ‘old school’ methods for creating – and promoting – their work?
Brian: I think the most important thing for any illustrator is to work on craft—practice their drawing. I’d suggest real pencil-on-paper drawing, because the feel is different from working on a tablet, but developing your own skills outside of an app or software is essential. You carry it anywhere you go. Promoting work is very different—I’m not sure there is such a thing as non-digital promotion anymore! We’ve done things like wrapping a vehicle with book images to draw attention at book signings, and creating hand-outs like stickers and temporary tattoos. But so much of the world’s promotional focus seems to be on TikTok, Instagram and other social platforms these days.
Me: Can you share what you’re working on next?
Brian: Happy to! My next book is called Diffy (fall 2026, Christy Ottaviano Books / Little, Brown & Co.), about a deep sea fish with a light similar to an anglerfish’s light, and what happens when a dictionary lands on a ledge of the seamount where he lives. It opens, displaying marginal illustrations he can’t understand—they’re completely outside of his world. Frustrated by not understanding them, he begins to group things together in his imagination and share his rudimentary stories with other fish. It’s essentially about how the human brain can’t help but try to find patterns and make sense of the incomprehensible by creating stories.
Me: Wow, can’t wait! Thank you so much for chatting, Brian, about your amazing book and process. Wishing CAT NAP much success!
