The Jolly Postman or Other People's Letters is an interactive children's picture book by Janet and Allan Ahlberg. The innovative project required five years to complete, and much discussion with both the publisher Heinemann and the printer before it was issued in 1986. The first subject heading assigned by WorldCat is "Toy and movable books". Little, Brown published a U.S. edition in the same year.

The Jolly Postman has sold more than six million copies, Allan Ahlberg told The Guardian in 2006. It made innovative use of envelopes to include letters, cards, games and a tiny book.^[2]

Alternatively, The Jolly Postman is a series of three books including 1991 and 1995 sequels to The Jolly Postman, or Other people's letters. In the U.K., the first book won the Red House Children's Book Award and the Kurt Maschler Award.^[3][4] The second book won the 1991 Greenaway Medal for British children's book illustration.^[5]

The Jolly Postman follows an unnamed mail carrier as he delivers letters by bicycle to characters from traditional children's stories that are well known in Britain. Following each sheet of narrative verse and illustration, there is one shaped like an envelope and containing one of the postman's deliveries. Each envelope is opened and its enclosure read at that point in the story.

WorldCat gives the entire description: "A Jolly Postman delivers letters to several famous fairy-tale characters such as the Big Bad Wolf, Cinderella, and the Three Bears. Twelve of the pages have been made into six envelopes and contain eight letters and cards. Each letter may be removed from its envelope page and read separately."^{[6][lower-alpha 1]}

The Ahlbergs won two major British book awards for The Jolly Postman, the 1986 Kurt Maschler Award^[4] and 1987 Red House Children's Book Award. The Dutch translation of the book De puike postbode won the Boekensleutel literary award in 1988.

From 1982 to 1999 the "Emil" figurines from Maschler publishers and BookTrust annually recognised the creator(s) of one "work of imagination for children, in which text and illustration are integrated so that each enhances and balances the other".^[4] The Federation of Children's Book Groups award (now named for the bookseller Red House) "celebrate[s] the books that children themselves love reading". The winner is determined by vote of British children.^[3]

Janet Ahlberg was a commended runner up for the 1986 Greenaway Medal^{[7][lower-alpha 2]} and she won the 1991 Greenaway for the sequel.^[5] The annual award by the Library Association then recognised the year's best children's book illustration by a British subject.

Following The Jolly Postman's success, the Ahlbergs and Heinemann produced two sequels. The latter, third in the series, was published after Janet's death in 1994. For the second book, The Jolly Christmas Postman, she won her second Kate Greenaway Medal.^[5]
