If Holland had art materials with him, you could be sure he would start sketching. On french family holidays, table cloths would be covered with drawings of the food, waiters, the scene if I took too long finishing my dinner. While others bought postcards or took numerous photographs, Holland would fill sketch books and any scraps of paper that were to hand with images of what he saw around him.
Not all of these sketches would then be turned into more formal paintings, but his studio would have these small drawings littered around and often mixed in with other correspondence if there had been a hasty tidying up session. If I wandered into the studio and commented on something, if it wasn't in a sketch book or planned for a full painting, I would often be given the picture to put on the wall of my room.
This simple black watercolour sketch is one of my favourites of this genre - showing a river estuary with a number of small boats dotted around. It could have been Cornwall, Brittany or Normandy, but is highly effective in depicting the scene.
