Drawings, aquerelles and pastels - works for auction

Perhaps you're drawn to the warmth of a sanguine, the softness of a pastel or the vigour of a Chinese ink? Sketches, studies, preparatory or finished works are all represented in these auctions: heightened watercolours, gouache or mixed techniques, rare drawings on paper or vellum, washes, three pencils, black stone, graphite, charcoal, white chalk... Older drawings are given pride of place, but you can also discover modern and contemporary works.
