"To put a painting like this on a yacht, with the sea air and the evaporation would be utterly stupid. I cannot believe the buyer would put this painting in a setting like that," Bouvier said. "It is on a wood board, which can warp in no time," he said, referring to the walnut panel on which the artwork was painted. Vitkine speculates that "it might be that we see it one day in the Louvre Abu Dhabi. Who knows?"
