20th Century Art in its Exhibitions: 1945-2007 is centred on the exhibitions which have generated new ways of seeing and expressing reality. These are predominately exhibitions of ‘thesis’, exhibitions which put forward new creative intentions and those which have manifested ‘the spirit of the times’; exhibitions which have stirred up creative debate; those which have been capable of expressing the cultural meanings of art; those which have, ultimately, been conceived as questioning the style, languages and discourse of the plastic arts, but which also question the intentions and artistic positioning of our era.
