"This famous manifesto, which first appeared in 1937, has been unobtainable for many years. It is now reproduced, with a new introduction, for recent generations of students and for all those interested in the history and development of modern art. At the time of its original publication, Circle proposed not only to bring the then new constructivist ideas to the attention of the general public but also to give their major exponents 'the means of expressing their views and of maintaining contact with each other,' to provide a 'medium for the interchange of ideas.' From this it will be seen that the artists involved were not members of a formal movement but represented various tendencies that, when juxtaposed, were found to have important similarities, both stylistic and theoretical ... In addition to the well-known editors, an unparalleled host of now famous artists, critics, and theorists ... has provided written contributions, and their work is generously reproduced in the copious illustrations. With such ... rich representation of active participants, Circle can be said to seek and to arrive at the very essence of constructivism"--From back cover.
