Yeah, I wasn't going to mention that....

Typographers of the hot-metal era might have been concerned about keeping ink off their hands, but it's really not an issue with more recent technology! In any case, one would definitely not want to type in gloves. To reduce errors, practice, practice, practice.

No pain, no gain.

That question has been addressed well by other commenters, above; apparently it's a German standard. I noticed it wasn't QWERTY only after you'd asked and I'd zoomed in on the image. The clues to its typographic nature were a little easier to make out -- e.g., the alignment controls along the upper row, and the power-of-two fractions in the foreground, etc. Bethold machines could produce some very high-quality output, though I was was never a big fan of using them.

It helped to have worked in that field for a number of years. But I've never seen one quite like that before.

Huh. Some typesetting device, perhaps?

Try Naked Lunch by William Burroughs: you might view things in a whole new light thereafter.
