Souvenir Sheets

Over the years, the Swiss PTT has issued more than a dozen souvenir sheets, most of which were issued to commemorate and/or raise funds for philatelic exhibitions.

The first souvenir sheet was issued in conjunction with the Swiss National Stamp Exhibition (NABA) September 29, 1934

Fifty years later, this souvenir sheet was issued to commemorate another NABA in Zürich
