The Banque de l'Algérie et de la Tunisie was a transitional institution — Algeria had operated under the Banque de l'Algérie since 1851, but Tunisia's incorporation into the note-issuing structure formalized a colonial monetary union that was already under political strain by the time this series entered circulation. Tunisia gained independence in 1956; this note's issue window closes just before that rupture made the institution's dual mandate untenable.

William Fel's design was executed through the Banque de France's own printing workshops in Paris, with Marliat handling the obverse intaglio and Broutin the reverse — a division of engraving labor that was characteristic of the period's larger-denomination work. At this format and value, the paper stock was heavier than lower denominations in the series, and surviving circulated examples frequently show stress fractures along the vertical center fold.
