If, like me, you're into the work of Karl Bickel (senior), you may want to consider hunting down a copy of 'Der gute Menschenkenner' issued in 1976. It is a magazine wholly dedicated to the life and work of Bickel.
You would need to be able to read a bit of German though, for that's the language it is written in. But if you do, you'll find that it is rather an interesting read. The magazine deals first with Bickel's Paxmal, his peace monument, and the philosophies behind it.
After all, we are dealing here with a magazine issued by those who study physiognomy, or the practice of assessing a person's character or personality from their facial features. So we are very much dabbling in the fields of biology and psychology here.
Which is why the second half of the magazine deals mainly with Bickel's portrait engravings, whereby his talents to represent those facial features are praised to the hilt. Interesting detail: Hodler the painter, who needs to see, is depicted on Bickel's stamp with his eyes wide open, whereas the poet Keller, who's way more inward looking, is depicted with his eyes almost closed.
Anyway, you get the gist. No standard story on engraving techniques or this is what he did then and so on, but an original look on a man's work.
