At the request of the Bilgoraj Commune Office, a practical three-part wall calendar for the coming 2023 was prepared. The so-called "heads" of the calendar are decorated with two of my photographs presented below. Half of the edition is illustrated by a photograph taken in the Obara nature reserve, while the other half is illustrated by a photograph of a heath in the Solska Primeval Forest. The publication is part of the promotional campaign of the Bilgoraj Commune.
