Screaming ghost symbol in tex

I’m not aware of any LaTeX package that has Edvard Munch’s “The Scream.”

However, LaTeX lets you include any picture you want, and that one is in the public domain. The approach I would recommend would be to download the clip art as a SVG, such as this one Thérèse found, crop the part of it you want with a program like Inkscape, and include the SVG graphic in your document.

That will get you a vector graphic that doesn’t pixelate, but pixelation on a thumbnail would probably not be noticeable anyway. So you can use your format of choice.
