Karin by the Shore, Carl Larsson; watercolor, 29 x 21″ (75 x 54 cm). Link is to para on Wikipedia which links to high-res image file. There is also a zoomable version on Google Art Project. Original is in the Malmö Art Museum.
Another of Swedish artist Carl Larsson’s delightful scenes of domestic life. In this one his wife, Karin, walks along the shore of the Sundborns river while their daughter, Brita, floats in a skiff with their dog.
The credits list this as simply watercolor, but it looks to me like he’s used pen and ink as well.
