Generations of readers have enjoyed Wanda Gág’s Millions of Cats, and kept it in print ever since its 1928 publication. The book is memorable both for its text (with the repeated cadence “Hundreds of cats, thousands of cats, Millions and billions and trillions of cats”) and for its book design, pioneering the use of illustrated two-page spreads. You can see samples in Emily Temple’s Literary Hub review. Millions of Cats will enter the public domain in 46 days. #PublicDomainDayCountdown
