[#1043]Ich habe etwas über die von dir gezeigte Doppelkarte in dem Aufsatz über die Pariser Rohrpost von J.D. Hayhurst gefunden. Dort wird das Wertzeichen als 'Chaplin-Design' bezeichnet:
"... The first are those for withdrawals from the Caisse Nationale d'Epargne in the rue St Romain and consist of reply-paid forms, part for the applicant to complete and part for the Caisse to return to him with authority for a withdrawal. They appeared in 1884 as joined cards and then as folded forms with varying texts between 1890 and 1904 all with a black Chaplain stamp of 30 centimes. In 1909 the Sower stamp replaced the Chaplain design as had happened with the standard postal stationery …" (

Die von dir gezeigte Doppelkarte sollte also aus der Zeit von 1890 bis 1904 stammen.
