An "Ermine Mustela" on the right. A stamp from a 2020 set titled "Winter Animals". And next to that a stamp from the 2021 set "Precious Nature". The five stamps in the series promote environmental protection and feature nature scenes by artist Henning Trollback. And the pair of stamps on the left are from a 1977 booklet featuring wild berries of Sweden. They look like lingonberries.
