On 1 January 1957 the P.T.T. Saarland was transformed into the Oberpostdirektion Saarbrücken of the Deutsche Bundespost. The return of the Saar Area to German control was commemorated on 1 January 1957 by a special stamps, then followed shortly thereafter by definitives with the then-standard profile of President Theodor Heuss, and inscribed both "SAARLAND" and "DEUTSCHE BUNDESPOST". The numerals did not indicate a monetary system, but were implicitly francs; later in 1957, the stamps were reissued with a small "F" after the numeral.
