Portret van een onbekende Groningse student in maskeradekostuum c. 1880 - 1905

This cabinet card photograph, taken by Berend Mulder in Groningen, Netherlands, around the turn of the 20th century, depicts a young man in a masquerade costume. The sitter is likely a student from the University of Groningen, known for its academic traditions and student life. The man’s pose, the ornate costume, and the background's hint of a grand interior all suggest a formal portrait, capturing a moment of celebration or festivity. The image's small size and its inclusion of the photographer's name and location are characteristic of this popular format of the late 19th century.
