Here we have rare and very unusual bookends. Each bookend has a rippled face and the eye finds it difficult to resolve the pattern. An effect of rippling water is created. What did the sculptor intend? Apparently these are bookends in the style of Optical Art.
Optical Art was a style of abstract, non-objective art which used patterns or figures to fool the eye and create optical effects such as the illusion of movement. This art style grew up and regressed in the nineteen sixties, and we do not see much of it today.
These bookends are bronzed iron, five inches high, and with no inscriptions. We guess they date from the sixties. The artist and the foundry are unknown.
