This is a small vintage 1982 paperback illustrated children's book called Smurphony in C. The book is written and illustrated by Peyo and features their characters The Smurfs from comics and television. In this book the Smurf orchestra was going to play and Harmony Smurf could hardly wait to play his trumpet, but Harmony played terribly. All the pages of the book are intact. Along with the story are colorful illustrations to go with it. The outside of the book is worn around the edges and corners. It is part of a series of mini story books based on the Smurfs.
