The book, which the author dedicated to his brother Reto, is an autobiographical novel, which tells of his life and work as a travelling salesman and hawker.

The book was translated into Hungarian by Sándor Szathmári (Tréfán kívül, 1957). In 2013 the Milan Esperanto Club prepared a translation into Italian, which was then published by the Italian Esperanto Federation.
