I just love it. May not be digitized. 1932 Charles Scribner's if that helps.
Main title and author might be different typeface, look at lower case t, but I think they are different fonts in the same typeface.

Two points.
1. Lettering on book covers in the early decades of the 20th century, and before, were custom designs by lettering artists and usually did not reference a specific font.
2. The letter forms in this book cover reflect the lettering styles of the 1890s and 1900s rather than the 1930s. Perhaps this is a reprint?
The letters in the title are a pastiche of different styles. Creating something similar would require the excerpting of letters from various sources and editing to harmonize weight etc.
For _a_, _h_, _m_ and _s_ Verona TS Extralight is in the ballpark.

Yes, it is in the ballpark - really what I was looking for. That upper case H though... I'd love to find something like it.
