Exhibition of works by Sjak Wubben and Piet van der Linden; a performance by Franklin D. Aalders and a concert with 8 (or 10) guitar players. One of the posters actually announces concerts by De Helis and Jan de Jong, whereas the newspaper clipping announces a concert by the guitar player Jan de Jong from Groningen plus other bands. The photographic documentation suggest that there was also a concert by the group Ret Marut (judging from the paintings in the background). Ret Marut consisted of Henk van Schaik (tenor saxophone), Jola Meijer (euphonium) and Rob van Schaik (bass clarinet).
