Kalenderblad voor december 1913 met een oehoe en kerkuilen 1912

Theo van Hoytema's *Kalenderblad voor december 1913 met een oehoe en kerkuilen* is a detailed calendar illustration that captures the stillness of a wintry night. The artwork features owls as the central theme. The top of the design shows a large Eurasian Eagle-Owl perched on a branch in a stylized forest, while smaller owls, both Eurasian Eagle-Owls and Common Barn Owls, are depicted in the lower corners of the artwork. The calendar itself is situated in the middle with a subtle design of candles and moons bordering it, while a stylized depiction of the forest floor with owls and their prey completes the bottom of the illustration. This artwork is an example of Art Nouveau, characterized by organic forms, stylized nature, and a focus on the beauty of nature. The artist, Theo van Hoytema, was known for his woodcuts and illustrations, and this calendar design is a fine example of his skills.
