These four stamps were issued as joined pairs as part of a six stamp set – sadly I don’t have the 4 Zt value stamps – on 30 September, 1975 to celebrate the 100th Anniversary of Polish Mountain Guides.
The stamps feature scenes of mountains paired with flowers and were designed by well-known Polish graphic artist Alojzy Balcerzak.
1Zt – Tatrzanski Park and a gentian flower
