06 ALPES-MARITIMES. NICE. Action de F100. brown, blue. #26500. No 21547. A 'must' for any collector of Côte d'Azur material. Fine vignette and underprint of the Negresco, on the Promenade des Anglais, still perhaps the smartest hotel in Nice, and a chic social centre, for those who can afford it! Facsimile signature of Negresco, the founder.
