While in Edinburgh (see post below too) I bought a postcard from the National Galleries of Scotland showing The White Drake painted in 1895 by Joseph Crawhall. Unfortunately the original isn't on show at the moment, so I had to be content with the postcard, but i'm glad I spotted it.
The painting is watercolour and gouache on unsized brown linen, laid onto a wooden backboard. Crawhall was born in Morpeth, Northumberland and is chiefly known for his paintings of birds and animals.
I love this piece - the handsome duck wandering through a shaded field dotted with daisies and dandelions. Lovely.
