Ahem. Moving on. "The Scream," Munch's most famous painting by far, had a whole gallery devoted to it. Apparently, Munch painted (or otherwise composed) dozens of different versions of The Scream during his life. The museum displays three of them: an oil painting, crayon on cardboard, and a black-and-white lithograph. (Apparently, every single version of The Scream was either on paper or cardboard, never canvas)
