Portret van een onbekende man, vermoedelijk Martinus Marmelstein 1900 - 1940

"Portret van een onbekende man, vermoedelijk Martinus Marmelstein" is a portrait photograph taken by J. Kuipers, a Dutch photographer, between 1900 and 1940. The photograph depicts a man in a formal pose, seated with his left arm resting on the armrest of a chair. The man's attire suggests he is of a higher social class. The photograph's composition is straightforward and traditional, typical of portrait photography from this period. The photograph was most likely commissioned by the subject, and it provides a glimpse into the lives of the middle to upper class Dutch citizens during the early 20th century. The subject of the portrait is most likely Martinus Marmelstein, but this is unconfirmed, and further research is needed to authenticate the subject.
