Alexander Calder

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

- Alexander Calder, born 22 July 1898.

BIG RED (1959)

American sculptor best known as the originator of the mobile, a type of kinetic sculpture the delicately balanced or suspended components of which move in response to motor power or air currents; by contrast, his stationary sculptures are called stabiles.

The artist sent Pierre Matisse these instructions on the assembly and pricing (in bright red pencil) of sculptures for an upcoming gallery exhibition. http://bit.ly/ZKpi1E
