1842 City Despatch Post 3c, two celluloid clichés with mirror image in black and light gray, mounted between glass, dated Feb 1953 and Apr 1950 respectively, with Sperati’s comprehensive production notes written around the design, detailing the filter used, temperature and exposure times. A pair of fascinating working clichés of the typical Sperati type, with only one reproduction on piece contained in the “Ultimate” collection.
