Briefkaart aan Max Dittmar Henkel Possibly 1925

This is a postcard addressed to Max Dittmar Henkel, a conservator at the Rijksmuseum in Amsterdam. The postcard was likely sent by the artist Jacobus Henricus Maria Hagen, a Dutch painter, in 1925. The postcard itself is a simple example of a typical communication medium of the time, and could potentially offer insight into the working practices of the artist and his relationship with the conservator.
