At art studio, gallery and family museum Van Vlaardingen in Maartensdijk there is a permanent exhibition of paintings by three generations of Van Vlaardingen, Derk, Jan, Clement and Dick van Vlaardingen. Moreover, the gallery houses a private collection which has been built up by the family since 1908. The collection includes work by fellow painters from 'het Gooi', such as M.H. Mackenzie, Jan Rijlaarsdam, Stephan Kip and Bernard van Beek.
The whole collection contains around 150 paintings and water colours. Much of the work has been painted outdoors, often in a realistic impressionistic style.
