It's about time for this perfect gift for the Dalinian book lover! Diecut metal, this book mark is inspired by Dali's 1952-54 painting, 'The Disintegration of the Persistence of Memory.' He reinterprets the irrelevance of time and acknowledges the developments of modern physics, Einstein's theory of relativity and Heisenberg's quantum theory. Dali has painted this disintegration as moving in a harmonious pattern, indicating an underlying order in nature. 1 inch x 4 inches.
