This is a later text of an 1867 novel by Belgian author Charles De Coster. It's based on the 14th century Low German figure Till Eulenspiegel, and Coster's novel recounts the allegorical adventures as those of a Flemish prankster Thyl Ulenspiegel during the Reformation wars in the Netherlands.
The artwork does not look like any George Grosz work I've seen, but it does look like the work of a professional cartoonist and the subject matter appears to be political and satirical. The idiosyncrasies of the script make it hard to translate, but obviously Grosz's name does not appear
Here's a link to MOMA's collection of Grosz drawings:

However, if you have access to a modern art museum it would be interesting to find out more about your artist.
