I love looking at these books as they are some of the earliest I can remember reading. I love the font and would like to use it on the cover art for my second book. I just need help identifying which it is. Thank you all in advance! - D.J.

P.S. I'm new to this site.

Unfortunately, I don’t think any of type on this cover (save for “Author of…” and "The letters of death…,” which are Gill Sans Italic) was typeset—it appears to be hand lettered.
