On a recent trip to Bath I visited the beautiful bookshop Topping & Company. A Bath institution, Toppings hosts a comprehensive and ever changing collection of art and design books. A recent and favourite find is Calder by Matter; a beautifully made book which catalogues the work of American Sculptor Alexander Calder. The book features photographs of Calder at work in his studio and images of his projects. I particularly like the above images which are from 'Le Grande Cirque' (1927). Click here to watch the corresponding film which shows Calder using pulley systems to bring the model animals to life. The book is available to buy here.
