Ah, the power of the sketch, the immediacy of the scribble and the quick depiction. It’s something all artists do, have done, and continue to do. It’s really good to see so many of the works on paper which made by the impressionists gathered in one place. The Royal Academy in London has presented a very charming exhibition of works from Degas to Toulouse-Lautrec and everyone in between, showing how versatile and useful paper, of all sizes, has been for capturing the moment in pencil, charcoal, paint or pastel.
