I love weird pulp paperback covers, though I must confess I am not a paid-up aficionado like some of my friends. But this far and away the most bizarre book jacket I have ever seen.
Just imagine the pitch. "Okay, so it's about these nazi leprachauns, right..."
Apparently, the back cover blurb reads:
The Little People - Elves? Demons? They speak German. They carry whips. And they are connected in some mysterious way with Nazi experiments carried out in the charming old Irish castle during World War II.
For this I have to thank the wonderful Crud Crud.
