Hunebelle pieces are marked in several ways. The most common is A.HUNEBELLE-FRANCE in molded capitals either within the glass design or on the base. Other pieces are marked simply A.HUNEBELLE. There was also a paper label with A and H superimposed in a stylized manner. Since paper labels are frequently lost, many pieces may appear completely unmarked. In the author's collection there are pieces marked A.HUNEBELLE both with and without the word FRANCE, and a bowl marked MADE IN FRANCE that is identical to one shown in a Hunebelle catalogue. Hunebelle also used a more elaborate maker's mark imprinted on some glass pieces which had the word FRANCE encircled by the words MADE IN FRANCE MODELLE DEPOSE et R COGNEVILLE and with A. HUNEBELLE underneath (reflects mid 1930s partnership with COGNEVILLE).
