We saw the exhibition at the Tate Liverpool. My mum considered buying the book, it seemed quite pricey, but still tempting. I found it on Amazon much cheaper after the exhibition finished and my mum was delighted. For those who did not see the exhibition it combined later works by two artists that I was really familiar with (Turner and Monet) with later works by Cy Twombly, a 20th C artist that I was not really familiar with. The surprise was just how well Twombly stands up alongside the other two.
