Private postal stationery

Private postal stationery are cards or envelopes with the official Swiss Post stamp printed on them, which were additionally provided with advertising or views at private instigation.
Around the turn of the century (1900) these were used very frequently for exhibition cards and are generally much rarer than similar cards with conventional postage stamps.
