Kalenders voor januari, mei en juli 1904 1904

"Kalenders voor januari, mei en juli 1904" is a 1904 work by Dutch artist Theo van Hoytema (1863-1917). The artwork consists of three separate designs, each depicting a bird in a natural setting. The design on the left shows a white bird on a branch, the center features a similar bird in a more detailed setting, while the design on the right features a dark bird in a forest. The designs are likely meant to be used as calendars for the months of January, May, and July, respectively. The piece can be seen at the Rijksmuseum.
