In 1906, the Catalogue of the 10th Exhibition of the Society of Polish Artists "Sztuka" in Kraków, January-February 1907, was published. Weiss's lithograph used in the poster is reproduced as the catalogue frontispiece. It shows two herons clashing in flight over the body of a snake pierced by a brush. Like other animals hunting snakes, the heron represents the forces of good and wisdom. One of the most aesthetically refined Polish posters.
