I found this cool book about woodturning. The cover features a rare piece by Jens Quistgaard, abstracted shapes, and simple Helvetica type. It was published in 1970.
The book features a few more Dansk pieces inside and has a ton of information on how to make just about anything on a lathe. There’s a few dozen projects as well – none as cool as a Dansk pepper mill, but good stuff. There’s a lot of photos of wood and metal turned pieces inside as well, including works by Bojessen, Krenit, JHQ, and several others. The 2nd photo is a diagram I thought was very cool, showing the profile of many bowl and tray design projects.
