Never heard of Yeats as a painter, until Rudi Fuchs curated an exhibition with his paintings at the Haags Gemeentemuseum and it was a nice surprise. His painting is spontane , a little childish and impressionistic at the same time and thus resulting in a painting what is typical for Yeats with a signature of its own. The exhibition was not that large and i remember that the sizes of the paintings were not that large too.
What i do remember was the excellent catalogue Gracia Lebbink designed with the exhibition. It was one of her first lareg catalogues she made for the Gemeentemuseum but it has proven to be a classic and available at www.ftn-books.com
