After a decade of fan petitions, online campaigns and persistent calls for more official content from the beloved animated series Gravity Falls, Disney has announced The Art of Gravity Falls, an official art book set to release on September 15, 2026. The 256-page hardcover, co-authored by series creator Alex Hirsch and co-writer Rob Renzetti, promises to unlock the creative vault with never-before-seen development art, early character designs, unused ideas, storyboards, easter eggs and commentary from the show's artists and team.

The announcement, which surfaced in early March 2026 via Disney Books and Hirsch's social media, marks a major win for the dedicated fanbase that has kept the show's legacy alive long after its 2016 finale. Fans had long demanded an art book—petitions on Change.org dating back years urged Disney to approve a project similar to those for other Disney properties, arguing the series' intricate visual style and hidden details deserved a comprehensive visual history. Hirsch himself referenced a canceled 2020 art book deal with Dark Horse, fueling speculation that Disney's hesitation stemmed from concerns over demand. The new release through Hyperion Avenue proves those worries unfounded.

For years, the true origins of Gravity Falls have been hidden under lock and key. Now, for the first time ever, Hirsch and Renzetti crack open the vault to reveal the definitive visual history of the series. Inside the book, readers will find never-before-revealed development art from Hirsch's personal archives, including first inklings of Dipper and Mabel Pines, concept art of the strange town of Gravity Falls, storyboards from memorable episodes, every single one of Mabel's sweaters, lost episode ideas, cut jokes, deviously hidden easter eggs, and much more.

A foreword by animation legend James Baxter adds prestige, while interviews with the creative team provide behind-the-scenes insights into how the show's unique blend of humor, mystery and heartfelt family moments came together. The cover art, featuring iconic elements like the Mystery Shack and Bill Cipher, has already drawn praise on social media for its nostalgic yet fresh design.

Pre-orders opened immediately on sites like Disney Books, Barnes & Noble (with an exclusive edition), Target and Amazon. Fans quickly flooded comment sections with excitement, many noting the timing aligns perfectly with the show's enduring popularity on Disney+ and the recent success of related books like The Book of Bill (2024), which became a bestseller and expanded the lore through Bill Cipher's chaotic perspective.

Gravity Falls premiered on Disney Channel in 2012 and concluded its two-season run in 2016, earning critical acclaim for its clever writing, intricate puzzles and emotional depth. The series followed twins Dipper and Mabel Pines as they uncovered supernatural secrets in the quirky Oregon town with their great-uncle Stan. Hirsch's commitment to ending the show on his terms—rather than dragging it out—left fans satisfied but hungry for more. Subsequent releases like Journal 3 (2016), Lost Legends graphic novel (2018) and The Book of Bill kept the universe alive, but an official art book remained the most-requested item.

The announcement arrives amid renewed interest in Disney's animated catalog. Gravity Falls consistently ranks high on streaming charts, with new viewers discovering the series through word-of-mouth and algorithmic recommendations. The book's release also coincides with other Disney animation tie-ins, including a graphic novel from The Owl House later in September 2026, signaling the studio's investment in celebrating its modern classics.

Hirsch, who voices multiple characters including Stan and Soos, has been vocal about the project's significance. In promotional posts, he emphasized the book's authenticity—no AI-generated content, just pure hand-drawn art and creator commentary. Collaborators like cover artist Iworrel and video creator Louie Zong contributed to teasers, building hype with behind-the-scenes glimpses and music from composer Brad Breeck.

Fans have already begun decoding potential hidden messages in promotional images, a tradition rooted in the show's cipher-heavy episodes. Social media overflowed with reactions: "This is the closure we've been waiting for," one X user wrote, while another posted, "Mabel's sweaters alone are worth the price." Pre-order numbers are expected to be strong, given the series' dedicated community and the success of previous tie-in books.

The 256-page (or 252 in some listings) volume positions itself as the ultimate companion for fans, offering a deep dive into the visual development that made Gravity Falls stand out. It includes early concepts that evolved into fan-favorite elements, scrapped ideas that could have changed episodes, and annotations explaining artistic choices behind the show's distinctive style.

For longtime enthusiasts, the book serves as both celebration and archive, preserving the creative process behind a series that influenced modern animation with its mystery-box storytelling and emotional core. Newer fans, drawn in by streaming, will gain appreciation for the meticulous world-building that rewarded close viewing.

Disney has not announced additional events like signings or panels tied to the release, but given Hirsch's convention history, appearances at events like New York Comic Con or San Diego Comic-Con later in 2026 seem likely. The book arrives just over 10 years after the finale, providing a timely milestone for reflection.

As pre-orders climb and fan excitement builds, The Art of Gravity Falls stands as proof that the show's mysteries—and its devoted audience—continue to thrive. Whether decoding new easter eggs or revisiting old favorites, fans will finally get an official peek behind the curtain of one of Disney's most cherished animated gems.
