Charlie Chaplin behind the camera circa 1917.
Just to give you a heads up, I actually prefer Leuchtturm 1917 notebooks way more than Moleskine. The paper quality is far superior (I got excited about Moleskine until I found even pencil shadowed through to the other side of pages...). Leuchtturm offer the same ranges of paper styles (squared, dotted, and lined), have the appearance of Moleskine, and are slightly cheaper. So if you're looking for a similar style with better quality I'd suggest them (I'm in the UK and got mine on Amazon)
