I an in a bind I need a stamp from Nevis year 2000 or 2009 which shows the inventor of the piano an Italian with no real stamp ever issued for him. Keepland also issued 2 stamps for him. My question, if I buy these how will I know they are the real Cinderellas and not just copies off of someones printer. ? Can Cinderellas be used in a topical exhibit? Any help would be appreciated
