‎First printing of Peano's correct and complete Existence Theorem. Peano first published the theorem in 1886 with an incorrect proof. In 1890 he published a new correct proof using successive approximations. The theorem is also known as Peano existence theorem, Peano theorem or Cauchy-Peano theorem. ‎
