Ransacking my old sketchbooks, I came across a couple of sketches of bridges; I know one is on the Isle of Wight, I'm not entirely sure where the other one was: maybe it's even another view of the same bridge. The one with the green tree is 12 x 17 cm, the rather more wintry one is even smaller, at 10 by 10 cm. Two Hahnemühle papers, the bigger one on their Rough Torchon, the other on Veneto.
Call me absent minded by all means, but as I used a couple of watercolour palettes, the portable type, with pans, and the colours aren't identified - I'm not sure what I used; but certainly Cobalt Blue, Ultramarine Blue, Burnt Sienna, a primary yellow, and Viridian.
