My photograph taken on the highest peak of the Polish part of the Bieszczady Mountains - Tarnica, was on the cover of the jubilee calendar published by the Bieszczady National Park. On 7 cards in the 48x68 cm format, there are 13 photographs presenting the extraordinary values of the Bieszczady nature. The calendar was prepared on the occasion of the 50th anniversary of the establishment of the Bieszczady National Park, falling in 2023.
