A Moleskine in There Will Be Blood
There are little peeks at what looks like a pocket-sized notebook, but there is a scene where Day-Lewis’s character is in a meeting with some bigwigs when he slaps his notebook down on the table. It lands, and the camera stays on the view so that you can very clearly tell the telltale signs of the pocket Moleskine, with its hardcover black cover and elastic band!
Moleskines have been around for “two centuries”, so I guess this may be period-correct.
