I was interested in this book because of the author, but the lettering on the cover closed the deal... can anyone tell where the face is from? I'm pretty sure (from the scaled-up lower case) that it's not custom-drawn.

Now at least we now the name, this typeface showed up here in typophile before with no luck, scroll down a little.
Amelia, also shown in the link above, is the closer in the style that I have found, digitized or not. Beeing kind of close in time, could it be from the same company or designer Stanley Davis? I know it doesn't mean much, just a monday thought.
