I returned home this morning from almost three weeks in the USA where I visited a number of cities and their various collections of contemporary art (as well as a few other things).  I took this photograph in the ICA in Boston, where the artist had hung two chairs on the wall to be contemplated like a painting.  So much easier than actually painting something, like Vincent Van Gogh, who painted three views of his bedroom (with its two chairs) in Arles.  They were all on show in the Art Institute of Chicago, where I saw them on the final (rainy) day of the exhibition, so it was especially busy.  I don't know what Vincent would have made of the Boston exhibit but I'll guess that Marcel Duchamp would probably have approved.
