The Belgian Coffee Hag albums are unique, as they are issued in two languages, Dutch ("Wapens van het Koninkrijk België en het Groothertogdom Luxemburg")and French ("Armorial du Royaume de Belgique en du Grand Duché de Luxembourg"). The series of Switzerland and Czechoslovakia are also issued in two languages, but the albums themselves are bilingual; for Belgium two separate series in either language were issued. Each series consisted of three small albums, with loose sheets. Per sheet 9 arms were shown, with the description and some background on the back of the sheet.
