El Trabajo Perfecto is a 1976 Sesame Street storybook featuring Ernie and Bert, published by the National Textbook Company. While the book is written in Spanish, it was produced in the United States for use with Spanish-speaking children in America. The National Textbook Company partnered with Children's Television Workshop in 1976 to produce educational materials for Spanish-speaking students; the sets also included filmstrips, audio cassettes and student activity books. They go to the airport, where Ernie tries out being a pilot, but finds that he's afraid of heights.
