Alexander Calder is one of the world's most celebrated sculptors. Best known as the inventor of the mobile, Calder redefined sculpture through introducing the element of movement to his works. In addition to his mobiles, Calder also created static sculptures, called 'stabiles', as well as paintings, jewellery, theatre sets, and costumes.

'[A] lovely, well-curated collection of Calder's work.' – Kirkus'Aside from being nice and mathy, it's actually quite engaging and beautiful.' – Fuse8 blog'Here's another in this fine Phaidon series ... Like the other titles in series [...] it's a substantial board book just right for very young readers plus – for adults – a list of the works illustrated ... This is certainly a book that children and adults can use together. The Calder mobiles, both hanging and freestanding make very bold and appealing images to catch the attention, and the text introduces simple number games based on the sculptures illustrated on that page ... There's humour as well ... If you've acquired any of the other titles in this series then this will certainly be a worthy addition to your collection, and if you haven't, then it can be a good place to start.' – Montessori International
