Small watercolor of the Frisian waters with boats, vintage

A small watercolour of a Frisian lake with boats coming into the harbour and boats leaving the harbour. It was painted by a Frisian who was obviously crazy about water. For on the wall in the houseboat or for in the holiday home in Friesland. The small acrylic painting is behind glass and is framed with black cotton around the glass. This was done more often in the past, simple and fun. See also the extra photos.
