Perhaps pedantic but to me "Picasso’s Great Anti-war Mural Flopped" sounds like a story about a crappy painting while "How Picasso’s Great Anti-war Mural Flopped" sounds like a story about the situation and circumstances surrounding the painting. But I agree that with or without the "how" they're both pretty click-baity titles.
