Clausen started exhibiting at the The Royal Society of Painters in Water-Colours in 1889, rather late, and between 1889 and 1943 showed nearly 400 watercolours there. Here is a complete list of them.
The Society of Painters in Water-Colours was founded in 1804 and relaunched in 1820, after allowing oil paintings at the exhibitions of 1813-19. It became The Royal Society of Painters in Water-Colours in 1881. Later it was called The Royal Watercolour Society, but I don’t think that was in GC’s lifetime: the sources I’ve checked differ on that; it is the RWS now. It was informally called OWCS, or The Old Water-Colour Society, to distinguish it from the less prestigious NWCS, founded as The New Society of Painters in Water-Colours in 1832, and from 1863 called The Institute of Painters in Water-Colours, and from 1883 The Royal Institute of Painters in Water-Colours: a different entity.
In GC’s time the Society’s premises were at 6 Pall Mall East, but it moved to 26 Conduit Street in 1938.
The Old Water-Colour Society’s Club, from whose annual volume I’ve quoted,
was related to OWCS and founded in 1923: it produced volumes of essays
by artists and academics relating to watercolour artists from 1924 until the 80s or 90s.
There is every possible style in the series, and in most an understated Clausen poetry. A “Memorial Group” of five watercolours represented the late Sir George Clausen at the Spring Exhibition in 1945: the last bow of the grand old man at the threshold of post-war Britain.
The second of the 400 was Boy Trimming a Hedge, a late Bastien-era piece. The later ones rarely contain figures.
