I found a Flickr article from Danmarks Rockmuseum (Danish Rock Museum, nowadays Museum Ragnarock) on Holler forstærker (Holler amplifiers). According to the article Holler was a co-operation between Svend Olaf Møller and Holberg Radio, starting 1963-64.

filming of a Danish movie, "On A Saturday Night".
