The earliest releases from the period 1982 to 1984 have no dedicated logo, at most a simple inscription "Olga" in plain letters. In 1984 Olga Production was renamed to Olga Musik. At that time a dedicated logo was introduced with an old English sheepdog and the slogan "En hund efter god musik" (English: A dog after good music). In 1986 a proper "Olga" logo was introduced with "Olga Musik" as sub-title.
