Example from a book published in Haarlem, 1838, “Gedichten van Nicolaas Beets” 
— you will even see thin spaces before commas, like in France in the 17th-18th 
century.

The first books where I saw all thin spaces disappear were printed in the USA in 
the 20th century, after 1910 but certainly before 1960, so before digital 
publishing, but I am no specialist of type history.

I guess that they unfortunately were no typographers. It is true that there 
are at least two different schools on this subject. I will explain all that 
when I have a bit more time.
