White Ball is an abstract silk-screen and copperplate engraving print on heavy paper, realized in 1973 by the Japanese artist Shu Takahashi. Not numbered and not signed. Good conditions except for discoloration on the colored part of print. Shu Takahashi was a unique Japanese visual artist who also worked as a professor of the Kurashiki University of Science and The Arts. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
