Kalenderblad voor september 1914 met een eend op het water 1913

This calendar page for September 1914, created by Theo van Hoytema in 1913, is a fine example of Art Nouveau. It features a duck swimming beneath leafy branches at the top of the page, and a line of mushrooms in the bottom border. The central focus is the calendar itself, rendered in a simple grid with delicate illustrations, such as a pine cone, a fern, and the sun and moon to represent the days of the month. This calendar design is an intriguing fusion of nature and functionality, highlighting the aesthetic of the early 20th century. The artwork is currently on display at the Rijksmuseum.
