In his planned book "Funny Stories about the World Jamborees", which is still to be published, Hartmut Keyler has presented all 25 world jamborees in eight humorous graphics. One drawing per jamboree was selected from this book and published as a special collection of postcards (in a special format and in a hardcover box).
