Sextra is a brand name associated with a 1968 logo credited to Belgian graphic designer Paul Ibou. However, verifiable documentation specifically linking Ibou to a Sextra logo, or confirming the brand’s audio industry connection, could not be located in available sources. The following information reflects what is reliably documented about Ibou’s broader design practice and the context in which such a mark would have been created.
Design and History
Paul Ibou, born Paul Lodewijk Henri Vermeersch in 1939, began working as an independent graphic designer in 1962 under the pseudonym Ibou, derived from the French word “hibou” (owl).[1] Over a career spanning more than 60 years, he designed approximately 350 logos and symbols for corporations and public institutions.[2] His known clients include Cécémel, Antwerp-Tax, the province of Antwerp, the Universitaire Instelling Antwerpen, Tele-Onthaal, and the Belgische Tiercé.[3]
Ibou was recognized as a pioneer in developing clear visual identities for businesses and organizations in Belgium.[4] To convince clients of his designs, he created three-dimensional presentations of logos, known as logo-objects. These objects form part of his “logotheek” (logo library), which was acquired by Design Museum Gent in 2019.[4][1]
While the 1968 date and the specific design features of a Sextra logo cannot be independently confirmed through available sources, Ibou’s documented approach to logo design in the late 1960s involved bold, geometric forms and symbolic simplification. His 1967 logo for Antwerp-Tax, for example, demonstrates this style, as does his well-known 1983 logo for the province of Antwerp, which used fifteen triangles to form both the letters P and A.[4][5]
Meaning and Symbolism
Ibou’s broader body of work is characterized by letter-based marks and geometric construction, as reflected in his book Letters as Symbols, a collection of lettermarks from designers worldwide.[6]
