dc.descriptionColors of a collection set of postage stamps dated 1923 and corresponding to the hyperinflationary period of the German economy were identifiedwith Raman and X-ray fluorescence (XRF) spectroscopies. Molecular systems associated to the blue, green and yellow colours were characterized. Blue colour is Prussian blue (Fe4[Fe(CN)6]3) and the green colour resulted to be a combination of Prussian blue and the yellow/orange pigment (PbCrO4) or a yellow β-naphthol like monoazopigment. The XRF data suggest that ZnO was used as filler.en-US
