Patented in 1967, K67 was prepared for its serial production in 1968 with the first exhibition of prototypes in Ljutomer (Slovenia). In April 1970 K67 was published in an English design magazine with the article "Low life from the streets" and the Museum of Modern Art in New York included it into its collection of 20th century design. The K67 was sold in large quantities not only to the countries of Ex-Yugoslavia, but also to the COMECON countries and other continents (eg. Japan and New Zealand). Due to the fact that the K67 principle is copied several times by other companies, K67 came to embody the Eastern European kiosk culture.
