Hints: Yes, it’s a Picasso. Well, it was a Picasso. This happened to it last month in Montreal.

Answer: It’s Pablo Picasso’s L’Hetaire, painted in 1901, which was on display at the Montreal Museum of Fine Arts. The pink splash was the work of a man who has been identified only as “Marcel.” He is a member of the Canadian chapter of The Last Generation, a group of nutcases that believe they can save the world by destroying works of art.
