Techniques of modern art are discussed. The creative act in itself may be the work of art or the theory of art guiding the creation; conservation of these works is impracticable.

Packing and transportation of such objects requires careful planning and description for reconstruction. (See also 13-740, 13-741 and 14-994.) -- AATA
