Lost Dr. Seuss Book 'Sing the 50 United States!' Set for June 2026 Release

Editors found a near-final manuscript in UC San Diego’s Geisel Library, with new art commissioned from Tom Brannon.

Overview

  • Random House Children’s Books will publish the title on June 2, 2026, with a first printing of 500,000 copies.
  • The Cat in the Hat and two Little Cat helpers lead a mnemonic romp through all 50 state names, with a U.S. map tucked beneath the dust jacket.
  • Archivists uncovered a complete typed manuscript alongside a cover sketch, art-direction notes, and a loose page map that guided the finished pagination.
  • A nationwide First Book backpack program will place copies and school supplies in classrooms, with a music video and a Washington, D.C., celebration planned near release.
  • This marks the first full posthumous Seuss manuscript since 2015’s What Pet Should I Get?, though some scholars question whether the text was conceived as a standalone work.
