Bartlebooth's fifty-year self-erasing puzzle project
The rich Englishman Percival Bartlebooth spends ten years learning watercolour, then twenty years painting 500 seaports, one every two weeks. Each is cut into a 750-piece jigsaw by the craftsman Gaspard Winckler, reassembled by Bartlebooth, glued whole again, returned to the port where it was painted, and dissolved in solvent until only blank paper remains. He dies in 1975 at his desk over the 439th puzzle, holding a W-shaped piece when the only remaining hole is X-shaped, which reads as Winckler's posthumous revenge.
