Reproductie van verschillende foto's uit de omgeving van Paul Sandel te Bindjai Langkat op Sumatra, en een portret van koningin Wilhelmina, gebruikt als kalender 1890 - 1920

This anonymous calendar from the late 19th or early 20th century features a collage of photographs from the surroundings of Paul Sandel in Langkat, Sumatra, and a portrait of Queen Wilhelmina of the Netherlands. The artwork, which is now in the collection of the Rijksmuseum, uses photographs as a medium and showcases the diverse landscape and people of Langkat. This unusual calendar provides a glimpse into the life of a Dutch colonial subject in Sumatra during the colonial era.
