It is a typeface in the spirit of the Romantic era, maybe good for Romantic English poetry, though Štorm, probably with a chuckle, recommends it especially for German Romantic novels. Here is an excerpt from his commentary:
The expression of the type face is robust, as if it had been seasoned with the spicy smell of the dung of Saxon cows somewhere near Weimar, where the author had his type foundry in the years 1803-39.
(A font like this is also often called a ‘modern’, which obviously is an ambiguous term.)
P.S. I have a feeling that Walbaum’s metal type did not include a ‘Th’ ligature as shown here, but Štorm and some other font outfits (including Adobe) like to include them.
